There are still two cards being sold now which work well: * pcHDTV HD-3000 * AirStar HD-5000 The HD-2000 was pcHDTV's first card and should still work with MythTV, while the Air2PC-ATSC-PCI was AirStar's first card and should still work with MythTV. AirStar is the corporate heir to Air2PC. All the cards are simple demodulators when it comes to HDTV, none of them do any hardware decoding. Hardware decoding for HDTV is pretty deficient at the moment, there is a VIA motherboard chipset which some people have reported success with and a nVidia 5xxx chipsets work ok with Chromakey OSD, while the nVidia 6xxx and 7xxx chipsets are pretty sucky when it comes to HDTV playback. You'll be much happier with HDTV playback if you get a processor running at 2.8 Ghz or above and use software decoding. Make sure if you get an AMD chip that it is not rated at 2800+ but is actually running at a decent Ghz, something like a 4800+ will probably work. As far as which one the HD-3000 or the HD-5000 to get... pcHDTV has supported MythTV development, has analog-in as a bonus, and only costs about a dollar more. Both decode 8-VSB and QAM-64/256 and both will probably work just dandy for receiving HDTV. -- Daniel
