[mythtv-users] Can't get mythtv to read video from /dev/video0

Are you using OSS or ALSA. I always had problems with OSS and because there
was not audio/video sync, mythtv would appear to hang with a black screen.

If I select "Live TV" from mythfrontend, mythtv just seems to hang, and I have to alt-tab back to the terminal window it was run from and ctrl-c to quit. The same thing happens when I try to select the "watch recordings" option.
