[mythtv-users] mythbuntu stops working for no reason

[Dan Hayes]

My problem goes deeper than that though.  After a fresh install of the
machine, the front end works fine.  But after a few minutes stops working.
It never starts working correctly again.  Even after rebooting the machine,
the frontend will never again display a picture.  I just get the green
static and freezing every time I click "watch live tv"

I see errors in both the back end logs and the front end logs, but I don't
know what they mean or how to use them to troubleshoot.

The backend log gives the following errors:
2009-12-09 21:23:59.373 NVR(/dev/video0) Error: Resetting and re-queueing
2009-12-09 21:24:00.125 NVR(/dev/video0) Error: DQBUF ioctl failed.
                        eno: Input/output error (5)

The frontend log gives the following errors:
