[mythtv-users] Loss of sound from a PVR-250 after some random period of time

[Jason McMillon]

After some random period of time, the picture on one of my PVR-250's
locks.  I can return to the mythtv main menu and restart, but then
there is no sound.  This doesn't seem to happen on my other card.

Here is what is happening in my mythbackend.log:

2007-09-19 12:22:52.507 MPEGRec(/dev/video0) Error: Error getting
codec params using old IVTV ioctl
                        eno: Bad address (14)

Here is a copy of the startup logs:

Any idea where to go from here?
