    Same thing happened with both my HR20-700's. My playlists showed statements that said I had no recorded shows (or something of that nature}. After throwing a major snit fit, I did menu resets on both units, pulling the plug at the black screen, and after they rebooted, everything was back to normal. One other thing I did was unplug both eSATA drives. After a minute or so, I repowered the eSATA's then the HR20's. For all I know, this was not necessary, but I did it anyway.

    One feature supposedly implemented in the new software:
    • Unsubscribed channel s are colorized as ‘unsubscribed’ in guide
    needs more work.

    Some of my unsubscribed channels are marked but by no means all of them. HBO, for example, is marked, but HDNet is not, yet I get a "channel not purchased" screen if I try to view it.

    I thought I had read in the CE discussion on this release that it included support for having RF and IR enabled at the same time. I could be completely mistaken. As far as I can tell, this isn't supported. Anyone happen know anything about this?

    Thanks!

    Neither is better or worse. The chip that does the scaling for the 3:2 pull down is really the determining factor in the picture quality of 24fps (frames per second) video. 24fps is the frame rate for DVD and Blu-ray. one of the reasons HD-DVD owners loved their players was the quality of the chip that did the upconverting and 3:2 pulldown. Sharp has TVs that are 120hz so as to elimanate the need for the 3:2 pulldown. (other manufacture may now have this also). this way at 24fps, every frame is displayed 5 times. and with OTA that is 60fps each frame is displayed twice.

    Also 1080i and 1080p are seperate from 60fps and 24fps. You can have 1080i/24fps (early HD-DVDs and Blu-ray discs) and you can have 720p/60fps (ABC, ESPN).

    You could spend days at avsforum.com reading about the various output formats.

    Very pleased so far. My box updated at 12:35 AM right after all of my programs stopped recording. Also DirecTV2PC is working great for me. I would like other options like scheduling and the ability to delete shows after watching them but I'm sure that is coming.

    Well I just found out it won't let me play my FOX from OTA for some reason. Hmmm.

    At least in my area Cellular One was bought by AT&T Wireless which was later bought by Cingular which as later bought by AT&T. :confused: I expect AT&T to eventually spin off their wireless to some company named Cellular One so we can go full circle.

    Yeah, well, how about it?

    I was glad to see the introduction of DIRECTV2PC. Not because I have any use for it (which I don't) but because it just "has to be" 1/2 of MRV (Multi-Room Viewing). That is, now that an HR21 can stream a TV show OUT over IP, the "other half" of MRV is to be able to stream a TV show IN over IP.

    I could sure use MRV. As it is, the Female Unit goes around and schedules all of her favorite shows to record on all three DVRs.

    Not with the current platforms (HR2x). The video chips in these boxes do not have the bandwidth for 1080/60p (which requires TWICE the bandwidth of 1080/60i).

    A little perspective on 1080/24p would be useful here. This mode actually requires LESS bandwidth than 1080/60i (20% less bandwidth, to be exact). And the HR20 has ALWAYS supported 1080/24p for OTA recording. That's because 1080/24p is actually one of the 18 standard formats in the ATSC specification for terrestrial (OTA) digital broadcasting. All ATSC tuners are REQUIRED to support 1080/24p!

    (Not that any OTA broadcaster has ever actually broadcast in that format. Or ever will. Even though 1080/24p is the "natural format" for movies, it would be disruptive for broadcasters to use it, since they also broadcast video-originated material such as news and sports. Hence broadcasters can be expected to stick to the two standard high-def video-oriented formats, 1080/60i and 720/60p.)

    Prior to 0x0290, the HR20 could (in principle, not in practice) record an OTA broadcast in 1080/24p (all programming is recorded in the format in which it is received). On playback, such a broadcast would be converted to 1080/60i (via 2/3 pulldown, the standard way that movies have been converted to video since the dawn of time).

    What is new in 0x0290 is that the receiver can now (optionally) "skip the conversion to 1080/60i" and send the recorded 1080/24p material directly to a compatibile TV over HDMI. And the receiver can now accept 1080/24p programming over the Internet for "Video On Demand" — and in the future, it is quite conceivable that some PPV movies might be broadcast in 1080/24p. This "new support" is actually a "bandwidth saver" for DirecTV, and that is especially helpful in the case of material delivered over the Internet.

    Only the very latest TV sets (such as LCDs with 120Hz capability) can actually process 1080/24p over HDMI. (The fast 120Hz video refresh is not really a requirement, but they chose that because it is the least common multiple of 24 and 60. In fact, the "real issue" is that older sets cannot SYNC to an INPUT vertical refresh rate as low as 24Hz. If they could, it would be okay to display the material at an OUTPUT vertical refresh rate of 48Hz or 72Hz.)

    So, what are you missing if your TV set cannot display 1080/24p? Not much, really. Any such programming will be passed to your TV set as 1080/60i and all current TV sets have "inverse 2/3 pulldown" circuits that effectively reconstruct the fields into frames — so what you actually "see" is (effectively) 1080/60p. The only difference between that and 1080/24p is slightly uneven display times of alternate frames (they will alternate between 2/60 second and 3/60 second). This phenomena is known as "micro-judder", and most people can't even "see" it. I know I can't.

    By the way, the exact same issue arises with high-def DVDs (Blu-ray). Nearly all movies on Blu-ray are recorded at 1080/24p. Newer Blu-ray players with newer TV sets can actually display them at 1080/24p. But in most cases, the player outputs either 1080/60p or 1080/60i (which the TV set displays as 1080/60p).

    Hope this helps!

    Yeah, I have to agree with the timing of the update. My box rebooted at about 6:20pm last night, causing me to miss the weather segment on the local news (the only reason I watch!), then the software d/l during primetime... Killed my viewing experience yesterday.

    I'm glad to be rid of 0x254, but couldn't the software update have happened a little later in the evening? I'm curious what the motivation for a primetime update was.

    Sorry, there is no feature in the software for any HR2x receiver that permits both IR and RF to work simultaneously.

    All of the previous comments were correct...however, it should be noted that ALL 1080p sets operate in either 1080p/60 or 1080p/120 (with only some newer flat panels supporting the latter at the moment).

    So 1080p/24 WILL be converted to 1080p/60 or 1080p/120 by the TV, no matter what DirecTV does.

    What's with these lock-ups? My DVR was locked-up again, and I discovered that only too late. The new episode of Fringe did not record.

    Well, finally got things to work. After multiple soft and finally a hard reset, it let me select 480p, start playing a recorded show and then switch to 1080i. After the first program worked, successive shows started fine at 1080i. Problem solved, but quite disappointed with Directv's performance yesterday.

    All that said, the new guide speed is a nice improvement. And I like the changes to the Prioritizer.

    On my HR20, I got the message about 1080p and other features being added and also found the 'upgrade' to my recordings (all deleted) and my record series prioritizer items (all deleted). Seems to me that DirecTV should credit me back some subscription days for the faulty service.

    Nitpicking, but not entirely true, as there are Pioneers and others that do a simple 3 multiple to 72 Hz or a 4 multiple to 96 Hz. There is a difference between showing multiples of a 24 Hz signal to reduce image flutter and converting it to 60 Hz (which requires 2/3 pulldown).

    Playing video from my PC across the network just brings up endless Parental Notifications. I can get rid of them by doing a Parental off for 4 hours, but the videos also have no sound at all.

    What's DIRECTV2PC?

    Well ... not exactly.

    I've heard that there are some plasma sets that display 24p at 48Hz or 72Hz. But I have not confirmed it.

    However, I am sure about the Sony VPL-VW200 projector. This projector uses SXRD panels (Sony's version of LCoS, which you can "think of" as being "like LCD, but without the screen-door effect"). The VPL-VW200 is rated at a 120Hz refresh rate, and, indeed, it does use that rate to do motion-adaptive de-interlacing of video-originated material.

    But for film-originated material, and 24p in particular, the VPL-VW200 uses a vertical refresh rate of 96Hz. That is because 96Hz is an even multiple of 48Hz, which 120Hz is not. Why does that matter? Because the VPL-VW200 has several "film modes" that actually insert dark frames in an attempt to emulate the "flicker" of a real film projector!

    (For the uninitiated: movie film runs at an "input rate" of 24 fps, i.e. 24Hz in "electronics terminology". But film projectors SHUTTER each frame TWICE, so the "output rate" of a real film projector is 48Hz. This is done to prevent overheating of the movie film. And, of course, a mechanical shutter necessarily "blanks" for almost as long as it "shows" — which is useful for its heat control side-effect.)

    Another exception that I know about is the so-called "HTPC". Many people use computers to show movies, after the frames have been reconstructed by "inverse 2/3 pulldown" (also known as "inverse telecine"), at 72Hz rather than 60Hz. They do this in order to prevent the "micro-judder" effect — that is, at 72Hz all frames are shown for an equal duration, which is 3/72 = 1/24 second. To do this, you need a TV monitor or projector that can handle a 72Hz refresh rate — but those are not hard to find.

    When I push 1080p/24 via my HTPC to my Sammy plasma the display Info says it is displaying 1080p/24.

    About time?? I think when the banner is done displaying, the silly XM Graphic should be replaced with a fluid visualizer, which you can set a time delay to go to screensaver. They can do it on a cell phone, I'm sure they can do it on my HD DVR!
