[mythtv-users] HD3000/FC4 not working

[jason]

I spent most of last night looking through the list archive and googling 
but still can't make headway with my setup.  If I missed something please 
feel free to tell me to RTFM, as long as you point me to the FM.

I'm setting up 0.18.2 on FC4 using an Nvidia 5200-based card and an 
HD3000 with an OTA antenna.  The system is an Athlon 1700+ with 512MB of 
RAM and the latest FC4 kernel and nvidia drivers.

I followed Jarod's FC how-to and I have myth installed and configured but 
a couple of things are still wrong.  After a reboot I have to manually 
modprobe cx88-dvb then chmod /dev/dvb/adapter0/* so that the mythtv user 
can read the video card.  (The latest HD3000 firmware is being loaded.) 
Once I do that, if I tell myth that the card is a standard v4l it'll pull 
in stations but the quality is far worse than with a TV hooked up to the 
same line.  It won't let me do a channel scan when set as a standard v4l 
card and the audio is often out of sync with the video.

When I set the capture card type as dvb it'll do a channel scan and find 
plenty of channels and they do come in very clearly, but they stutter a 
lot even though the CPU load is only about .75 and there is at least 100MB 
of free RAM. But it doesn't find most of the standard channels that come 
in (albeit fuzzy) in V4L.  Also, the audio that comes through the HD3000 
when in V4L mode isn't there in DVB mode.  No TV audio comes out of the 
sound card, a chaintech 7.1, though Linux is able to use it just fine. 
It's possible that myth is sending the audio to the S/PDIF port but I 
haven't had a chance to check that yet.

Any pointers or help would be greatly appreciated.
