[mythtv-users] Re: Black screen after half an hour recording

[gkanis at cems.umn.edu]

From the settings --> General Playback I selected "Use xv picture control" and
then when I played the recorded movie, it becomes again dark, but now I have 
green and red colors in a black background.
Nevertheless, I disable the "use xv picture control" option and now when I 
watch live Tv, the colors are distorted .... instead of white I have a light 
blue color.
It looks like a bug ... what do yo think?
I will restart X and I hope it will change everything back to normal..
