    Fox is 720p.

    7401=Dish Network? What's this 7401 you speak of? (seriously, not sarcastic)

    And does it matter if there are no 1080p broadcasts?

    Ok, I know I have watched a football game in 1080i this year. Maybe it was that tragic and horrifying Cal game on Versus last week.

    It's the main processor for the HR21.

    CBS and NBC are both 1080i as well.

    CBS is usually 1080i. 720p is supposed to provide a smoother picture for sports because of the motion involved, 1080p would do the same. 1080i is said to be "choppier" - not sure if that's the right word, but close enough.

    Functionally, the biggest difference for me has been the color (it matches the rest of my system - yay!) and the ethernet switch, which allows connecting another networked device to LAN very easily if you don't have another ethernet jack handy. That network switch is probably the only difference you can really tell from a usability standpoint. Other things like the slightly larger drive and faster MPEG decoder are "nice to have" features, but other the physical appearance and different back panel layout, you'd never know you weren't using an HR20.

    I see, thanks for the insight. I hope we get 1080p soon; until then I guess it's 1080p dvd!

    The ethernet switch was extremely helpful. It allowed me to return the external switch and save $40.

    I suspect you have years of waiting ahead of you, as every HD national broadcast content provider spent millions and millions on 720p and 1080i equipment over just the past couple of years, and there has been virtually no mandate to even think about 1080p for several years.

    Add in the fact that 1080p sets make up less than 5% of the 30 million HD sets in the field today, and you only hear a yawn on 1080p right now.

    How's the HD noise compared to the HR20?

    Well, my HR20 is inaudible from my living room couch and so is my HR21.

    How's that for an answer? :p

    Lucky. I can hear a subtle high pitch whine from mine when the volume is low. Gets on my nerves and the HR10-250 never did it. Love the black face of the HR21 though!

    My HR21 is definitely quieter than the R15 it replaced. I'm not really sure how loud my HR20 is because of its location, so that's a tough comparison for me.

    I would also add to LameLefty's sentiments that there really is no noticable performance improvement from the HR21 vs the HR20. If there is, I can't tell. It truly is an HR20 minus the OTA, along with the visual differences such as the piano black color and diffused blue ring.

    I don't know how you would really be able to tell, but I don't think the difference in drive capacity really amounts to much.

    Unfortunately, this is likely a slight defect in your drive. Probably falls within the tolerance specifications and some are going to be better than others. Having worked with a number of different devices over the years both at home and at work, I find the HR20 to be very quiet .. I cannot comment specifically on the HR21 as I do not have one. However, I suspect that the performance is even better than the best that I have seen because of the even quieter drives.

    The rate of growth of 1080p sets is very rapid. It easily triple in the next year (to 15% or greater).

    But as to 1080p OTA, it's difficult to see how that's going to happen when it currently isn't possible to squeeze a 1080p(/60) channel into a single ATSC channel slot. It's just too much data for MPEG2 to hammer into 6MHz (26Mbit).

    So even if channels could produce it (and I am told many shows are shot in 1080p right now), and networks could route it through their systems, it couldn't be broadcast.

    I think that some day the ATSC group will meet and talk about how to employ H.264 in ATSC channels in the future. At that time, they'll also define 1080p/60 as an ATSC standard (employing H.264). Then, maybe we'll see OTA 1080p. It'll be years.

    Until then the only uses for 1080p are:
    HD disc formats.
    Downloaded content.
    Directly connecting your computer to your HDTV via DVI->HDMI.
    Games on Xbox 360 and PS3.
    And as a great format for display of both 720p and 1080i signals without any loss of resolution.

    Which, honestly, is quite a lot. I can't see how buying a new non-1080P (/60) HDTV right now makes much sense at all (unless it is below 42"). I'll go even farther. Make sure it accepts 1080p/24 too (even if it isn't full 1080 resolution), if you're at all a fan of movies.

    It'll be the twelfth of Never. To broadcast in a new format you'd have to be willing to ignore the installed base and somehow interest everyone in moving to new TVs. Look how hard THIS jump has been. Maybe in 30 years, and to 6400x2700 or some such. Media, computers and networks may have their own evolution of course, and "TV" may well be obsolete by them. Certainly satellite TV will be, given fiber.

    The TV manufacturers would like us to believe that, but even they can't forecast future buying habits. Some manufacturers are reporting sales lagging behind projections just in the past quarter alone.

    The adoption rate of HDTV in general is already behind "expert forecasts" from just 3 years ago, so there is no reason to believe much beyond 3-6 months in the future. It's kinda like the weather....you have a 50% chance of being right most days.

    With the 2009 deadline approaching, things will pick up because of that, not the 1080p standard. Many people with HDTV's today still don't even watch HDTV, they watch analog stations on their HDTV (as sad as that is).

    For all those reasons, there's no urgency in the market to migrate to 1080p broadcasts for 4, 5 or more years down the road.

    Is this any different than HR20-100? I have the -700 but thought I read that the HR21's ethernet is just like the HR20-100. Thanks.
