someone's WIKI once we get core information in one location:


Subject: HDTV, Myth, and you...

Hardware:
-- Do the HD-2000 work better, or are better supported than the HD-3000 cards?


The HD-2000 has probably been hammered on more, but several people are now successfully using the HD-3000. I have both, but the HD-3000 hasn't made it from my development/testing platform into my production system yet. Both are currently supported by MythTV.

-- Are there any other cards which do OTA ATSC HD recordings?


Air2PC-ATSC-HDTV http://www.cyberestore.com/product_info.php?cPath=28&products_id=103 . It is about $20 cheaper than the pcHDTV, but it doesn't support the A/V input (bttv). Don't know if the Air2PC will be able to support QAM. Scroll all the way to the bottom to see drivers/howtos and MythTV mentioned. This is currently not supported by MythTV (neither .16 nor CVS) unless you add Taylor Jacob's big DVB patch. See his site for more information. http://www.digitalregime.com/mythdvb . I also have this card, but haven't been able to spend any time on it. At this point I'll probably wait until Taylor's big DVB patch gets into CVS before spending any more time on it.

-- Which cards only work for DVB? Which only for OTA?


Don't know about DVB, but the HD-2000, HD-3000, and Air2PC work OTA. Don't let the DVB requirements for the Air2PC confuse you. It is an OTA card.

-- Which cards work with encrypted sources?

Playback:
-- How much CPU power is required to playback 1080i or 720p streams?


I can playback 1080i and 720p streams with a P4 2.8/533 Prescott (not-hyperthreaded) with an nVidia FX5200 card (without xvmc).

-- Are most converting down to 540p for playback? What steps are
involved in doing that?


I am. The only step was to use a 540p modeline that looked good on my old Samsung rear-projection (16x9 1080i).

OS:
-- What Kernel, IVTV/V4L/ are recommended for:
-- HD-2000


Kernel 2.6.9 (some people report better results with 2.6.7). V4l is 2.6.9 with Kraxel 2.6.9-rc4 kernel patch.

-- HD-3000


Currently I am using 2.6.9 with pcHDTV 1.6 driver (no kraxel v4l patch, just plain kernel 2.6.9). At one time I was using 2.6.10 with a v4l snapshot (forget which one, Dec 17th maybe?) and customized (read hand-merged) pcHDTV 1.5 patch. Ran out of time so just trying to stick with stock as much as possible now.

From what I can glean, best way to succeed is to install the HD card
into a different backend (if you already have a backend with PVR-XXX's
in them) run a 2.6 kernel, and patch patch patch.


Not necessarily. My HD-2000 with the original HD-2000 drivers work fine alongside two PVR-250 running ivtv-0.2.0-rc3c on a P4 2.4/533. Can't give you any info on other combos yet though.

P.S. My site is very outdated by now unless you are only interested in HD-2000 with original drivers and ivtv in same system running a 2.6.7 or 2.6.9 kernel. http://thegeorges.us/mythtv
