Run this command:

fuser -v /dev/video0

to find out what program is using the video device and preventing mythtv
from opening it.

Matt,
fuser didn't provide any causes, but my troubleshooting finally
provided and anwer. Thanks for the help, anyway.

I finally figured out my problem with recording.
I am using a perl script to control my satellite box via serial port.
Using this program to switch channels seemed to cause a few glitches in
the sound/video when switching channels viewing "live" tv, so I made
the program run detached with "&" from the script I was calling.
I took out the & from the script and all is well again.

Thanks,
Mark

Mark,

I had a similar problem with an external script to control my digital
cable box. The solution was to change the bourne shell script which
calls the perl script into csh.
