[PROBLEM] no picture in live-tv just sound ?

Update:
after installing the mpeg codec stream is working correct!
Investigated the video file captured on the gigablue.
On the first view it said that it was a mpeg ts file on the gigablue, but after download
to windows, mediainfo told that the movie was coded in AVC,
That was the reason why I could play it in Xbian without mpeg codec

PS: I had several shutdowns and reboot yesterday on different actions:
- trying to playback a music dvd from folder
- switch program in live-tv
Investigating..
