[mythtv-users] Second Tuner Not Working

Sat Jan 1 15:21:38 EST 2005

I have a system (Fedora Core II) with a PVR350 and a PVR250.  The first
tuner works OK, but the second does not.  Here are the relevant logs and
config info:

When trying to enable PIP, the menu freezes on the screen and I get this
in mythbackend.log:
Error setting format
VIDIOC_S_FMT:: Device or resource busy

>From then on I can no longer exit live TV, change channels, or get the
menu to respond.

Here is the relevant part of dmesg:

/dev/video1 also attached to cable

Finally, here are the video devices:

Hopefully that's all the info needed.  Thanks in advance for any
assistance.
