Problem with v4l in MythTV

Problem with v4l in MythTV

[Harry Devine]

Hello everyone.  I'm new to this list (it's my first post), so I hope 
this hasn't been covered already.  I'm running Fedora 8 x64 and MythTV 
0.21 (fixes branch).  I have a pcHD5500 capture card and have it 
configured for the 2 available portions: analog and digital (analog via 
v4l and digital via DVB).  The digital portion works great, but the 
analog looks horrible.

When I try to tune a channel in MythTV, or watch a recording that was 
made via the analog portion, it looks very static-y and jumpy (a mix of 
snow and green lines on the right hand side) and the audio is very 
erratic.  I tried using tvtime to check the tuning, and when I tune a 
station, I get the first second or 2 of it, then it goes to an all blue 
background and a "No signal" message on it.

Any ideas on where I can start looking to resolve this?  I'm using 
kernel 2.6.24.5-85.fc8.  BTW, I see no errors in /var/log/messages, and 
I get messages similar to the following when I run dmesg:

cx88[0]:   iq f: 0x140000c0 [ write eol count=192 ]
cx88[0]:   iq 10: 0x00180c00 [ arg #1 ]

cx88[0]:   cnt2_reg: 0x00000000
cx88[0]/0: [ffff81004ccf4000/0] timeout - dma=0x5a835000


Thanks!
Harry
