[mythtv-users] Backend stuffed up in RequestRingBufferBlock

[Adam Biskobing]

Since I'm having what I think is the same problem.  Let me elaborate a 
little.  I've done some various tests, to try and track down the 
problem.  I think it is definately driver related, but as to what in the 
driver, I do not know.  I too can do the cat /dev/video0 test just fine. 
 But when I try an 'mplayer /dev/video0' it will play for a few minutes 
and then stop.  Mplayer stops recieving data.  Any idea why this would 
happen only when video is being displayed?  It happens this way in Myth 
also.  If I leave the box alone when it is recording, it does fine, 
records every show I ask it to, and has absolutely no problems.  If I 
try to watch something it has recorded previously while it is recording, 
it stops recording.  If I try to watch live TV, it will work for a few 
seconds, and then stop recording, usually with the Bakcend stuffed up in 
RequesRingBufferBlock message.  I have posted to the ivtv list on this, 
but haven't gotten anything back on it yet.  Hopefully someone here has 
seen the same thing, and has a solution for it.  This is of course with 
a PVR-250.
