[mythtv-users] Watching live TV video problem (blank/black screen)

[Ma Begaj]

LiveTV tries for around 10-15 to start itself, and it quits if does not work.

Running mythfrontend on the command line should show you the problem.

Are you able to watch TV with:
mplayer /dev/video0 or mplayer /dev/v4l/video0
