[mythtv-users] IVTV 0.4.2 and MythTV

[Brian Fischer]

I just upgraded my kernel and a few modules.  I can do a cat /dev/video0 and
my system will capture, however mythtv is just showing a black screen on
live TV.  I cannot capture with scheduled recordings either.  I updated ivtv
and ran mythtv-setup, but it didn't seem to resolve the issue:
