[ATrpms-users] Live TV in MythTV not working (ivtv.. big suprise there!)

[Matt]

No matter what I try I can't get live TV working in MythTV.  When I 
initially boot up I can get in and use it just fine, sound works, I can 
change channels etc...  If I exit out and come back in though it hangs 
with a black screen every time.  If have to kill mythfrontend from a 
remote machine otherwise the system will eventually lock up 
completely.   That leaves me with a completely dead zombie backend  
process I can't do anything about until I reboot.  Until then mythtv is 
completely dead.

Here's my setup:
 
FC5 (2.6.17-1.2145_FC5 x86_64, previous .17 kernel had the same problem, 
.16 no channel changing)
ivtv 0.7 + kernel module
nvidia 8762 (have a 6200 card)

These are the errors I get in mythfrontend (backend log shows card not 
responding error only):

I'm not sure where to even start with this....  Nvidia problem?  My same 
xorg.conf worked fine FC4 i386.  IVTV problem?  That driver is crap, 
something breaks EVERY SINGLE time I do a yum update.. seriously.. why 
is the quality control that bad?  MythTV problem? 

The invalid file and data wait errors I don't get at all.  The volume 
it's on is on a totally different set of disks then anything else and 
aren't getting touched at all.  They are local disks that run ~90MB/s 
too.  (Hardware RAID 5).. same setup as user FC4 where everything worked.

The "Couldn't get coloc key color" error, what's that one about?
