After answering the pool that I had not had any problems, today I got my first BSOD.

RBR and I am back up and running....

This version seems to be a step backwards.

Last week's boston legal had many of the clicking sounds.

There are audio dropouts on most shows.

Friday Night Lights and also Bones from last week both only recorded the final 21 minutes.

0x120 - 3 RBR's required in a row tonight!

What a piece of dreck!!!
I have been patiently testing/using/reporting on 0x120 since it's Beta release, and tonight it required 3, count 'em, 3 RBRs, due to the dreaded BSOD.

Why? Because I changed the channel!

I was watching OTA KLASDT Las Vegas (8-1) and I changed the channel to OTA KLVXDT (10-1) Las Vegas. First time, worked fine. Second time, worked fine. Third time, BSOD. MPEG4 locals, Sat channels, HD sat channels, recorded shows on SATA drive -- Nuttin' but a black screen. Waited 2 minutes, watching glorious blackness, then decided to move on.

OK, says I, I'll RBR -- cool, everything's working. Repeated the scenario above, and wham, BSOD.

RBR AGAIN, and everything worked, until I changed channels -- BSOD.

Third reboot, and everything was working, except by now, the shows that I wanted to watch were over. Thanks for a box that takes 7-10 minutes to re-boot.
================
It really seems that as releases 'age in the box', they become more unstable. Smells of a memory leak, or something of that ilk.
================

I really would like the HR-20 and 0x120 to work reliably, but as far as OTA, the combination really sucks. And, results from satellite-only aren't much better.

I'd watch the MPEG4 satellite equivalent channels, IF they were close to the same quality, but they are not. OTA rocks, Satellite HD locals looks like they need a dose of Viagra (soft and sputtery in comparison to OTA).

What's a customer to do??

Actually, I believe that was a Network problem, as far as I could tell.

OTA, West Coast Feed and local HD (MPEG4) all had the problem for me here in Las Vegas.

The problem was reproducible on my Samsung and RCA DTC-100 STBs.

I've had my HR20 for about two weeks and got 0x120 on 2/2. I haven't had any serious problems. I don't consider things like menu tearing or "pinky" bugs to be serious problems. I reserve that category for missed or unwatchable recordings or system hangs. I appreciate the added features of the HR20 compared to the HR10 and I think the picture is a little better on the HR20, both MPEG-2 and MPEG-4. It took me a while to learn the new user interface, but I consider that to be "playing" - more fun than work. I do have a few observations to share...

1. By their very nature, forums like this are filled with reports of people reporting problems (which I don't doubt are real for some % of users.) Most people who are problem-free don't bother searching for "help and support" forums on the web, much less bother registering and posting. I'm here looking for (and finding) information about my new DVR.

2. Some % (probably a pretty high %) of complaints about MPEG-4 locals are caused by the local stations themselves. The HD stations in my area (Birmingham) are only marginally competent and my experience between OTA and the MPEG-4 locals has been about the same in terms of bad sync between audio and video, SD content for HD shows, missing audio, etc. A lot of these problems have nothing to do with D*.

3. The performance of the HR10 and HR20 on national HDs out of New York are about the same - occasional dropped audio, pixelation, etc. There do seem to be some video situations in which the MPEG-4 compression gets overwhelmed, at least at the current compression settings, but that's the nature of compression, especially of live video feeds. This will only improve when D* can increase the bandwidth of its channels when the new satellites come on line. Even as it is, I think it's acceptable. We should remember that we're watching TV - most of it's like popcorn - quickly eaten and forgotten. An occasional glitch during the "golf tournament of the week" is no big deal.

4. Since I've read so much negative stuff about the HR20 I'm still using my Season Pass list on my HR10 as a backup, so I can compare the two on an even basis. I've checked and the quality of the recordings is about the same and I haven't had to (or even wanted to) watch the backup copy of anything yet.

5. I teach electrical engineering at the University of Alabama in Birmingham and I've taught both coding theory (which covers things like MPEG compression) and embedded computers (which the HR20 is.) I know first-hand how difficult the job is that the HR20 is trying to do and frankly I'm impressed at how well it performs.

6. The frequent updates of the system software by D* seems to me to indicate two things. First, there are still a number of issues outstanding, and second, that D* really wants to get this right. Remember how long it took to get version 6.3 for the HR10? That's indifference.

7. I also realize that I may just be lucky and that my luck may run out at any time. If it does and the HR20 becomes a problem, then I reserve the right to be unhappy. Until then, though, I think it's an impressive and worthwhile product. :)


Welcome to the forum!

I would agree in principal with most of your observations, however, as a person that has tested several releases of the software on the HR-20, I would advise you to wait 2 weeks or so, and then reflect on your points above.

Specifically:

1) Yes, there are some whiners here, but by-and-large, I believe that we are reporting problems in the spirit of providing D* with as much information as possible so that they can create new downloads that are more stable and meet the written description of the operability and feature set of the HR-20.

2) I would not necessarily blame the Engineering staff at the locals for poor MPEG-4 performance. In my case, the difference between OTA local broadcast quality and re-distributed MPEG-4 is markedly different; that is, the OTA signal is constantly BETTER, by a large margin. Higher video frequencies (i.e., a crisper picture), no "stuttering" (motion artifacts & what appears to be dropped frames and smeared motion artifacts), sound quality & consistency.

3) Improved MPEG-4 bandwidth allocation and prediction algorithms are surely required on the part of D*; in addition, until the additional 2 planned satellites are launched and operational, limited bandwidth is, I believe, the main gating factor to improved MPEG-4 locals. This issue will, in my opinion, be addressed as we move forward.

4) I have a DTC-100 HD receiver that (via modification) allows me to record the raw HD bitstream to a HD, and I agree that the HR-20 does record "faithfully".

5) I too am greatly impressed by the HR-20 and what it can do, when everything works as advertised. I think about the complexity of recording up to 3 bitstreams simultaneously, while decoding and outputting a 4th, and it really is quite a feat of engineering. My background is in computer networking and protocols, and a device of this capability is awesome.

6) Agreed. This is evidence of an organization trying its' best to satisfy their clients. One could argue that the HR-20 was 'pre-released', but after reading these posts for several months now, I honestly do not believe that any organization could have released such a product/technology so advanced without flaws. In my view, D* has created the PC, Operating System, Applications, Networking and an Advanced U/I all at once. It "only" took the computer industry 35+ years to do the same things!

7) As I said in the beginning of my reply, the HR-20 seems to really preform well for a few days, and then the nasties arrive. Dunno if it is a memory leak, embedded L*nux, file system or other issue(s), but the boxes do seem to become more unstable as time goes by.

Thanks for your comments!

I've had audio dropouts with every release and up until this latest release I was forced to reboot the damn thing at least twice a week. I'd turn on the system and get the BSOD. Reboot and it was fine for a couple days, then nothing.

I don't watch that much in SD but the PQ definitely is not as good on this release.

I am getting red dots flashing at various times all over my display. I went to the direct tv forums and there were a lot of people having the same problems. At first I almost had a heart attack thinking it was my plasma.

It only started happening after Thursdays software update.

I just got the HR20 installed yesterday. Would I have gotten the 120 update when they installed it? Need to know if I need to download it. Also, I don't have an internet connection hooked up to it. Is that a problem?

Thanks

If the installer didn't force a download of 0x120 as the last step of the install, it likely downloaded automatically overnight. You should be good. A quick check under Menu->help & settings->setup-> info (hit select on the info) will tell you many things about your HR20 including temperature and the software level.

Nope you do not need either phone line or network for the HR20. Without phone line you can't order PPV via the remote control, but you still can order via the directv website.

Cheers,
Tom

During the Superbowl I got severe audio dropouts on all commercials. It was fine during the game but on a lot of the commercials I could hear the background sounds but no voices and the other commercials it would cut out about every 2 seconds . I am using x12 software with optical connection and I even switched DD on and off with no change. I was watching on OTA 8-1 (Indianapolis) I have always used this channel with no problems and this is the only time I have experienced problems, after the game everything was fine again. Very strange any Ideas or did anyone else have this problem?


I had the same issue but only seemed to occur after rewinding some during the game to see something we missed - then fast forwarded to catch back. After doing that, the audio would severely drop out during commercials until I changed the channel then changed it back - that seemed to resync things.
