Just FYI, my configuration is almost exactly the same. I'm running Gento x86_64 on an Athlon 64 X2 3800+. So far as I can tell, the problems do not be architecture-specific. (i.e. they are the same for x86 and amd64 users).

Is the video reception only horrible on the lowband channels (frequencies below 108 MHz or so) or across the entire band? On my PVR-500, only the lowband channels (ones which overlap with the coverage range of the TEA5767 FM tuner) have problems on the first tuner. So far I have had no problems whatsoever (audio or video) on the second tuner, although I have not gotten around to investigating whether the reports of bad channel 45 performance on the second tuner affect me. > Of interesting note is a discovery about the sound on the second tuner: > occasionally while changing channels, the sound will come in clear (not > reproducible for any given channel).

I'm guessing something else on the card isn't getting set up correctly. I recall that on the PVR-350s, it was possible to tune FM from either of the antenna inputs, but not TV from the FM-only input. I sort of recall having to do something to switch antenna inputs when fooling around with FM, I'm wondering if somehow the card is defaulting to routing the TV antenna input to the FM tuner. It's been a looong time since I've touched the 350's FM tuner, not since I hacked in really ugly support for it at about the same time Hans added much cleaner support to the ivtv driver. I have a couple of ideas I want to try, I haven't gotten a chance to actually try them yet though. For one thing, the TEA5767 has two programmable TTL outputs, and the PVR-500 could POSSIBLY be using one of these to control antenna switching. I haven't had time to modify the TEA5767 section of tuner.c to twiddle those outputs though. Someone else mentioned having similar problems with the Windows drivers on the CD but not recently downloaded ones. On my 32-bit-only desktop box, the most recent Windows drivers work flawlessly. _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
