Hi,

I hope somebody could shed some light to my problem with tv-out. I have an HP laptop with S3 Inc. 86C270-294 Savage/IX-MV video card. I could switch back and forth between LCD and TV displays with the command "s3switch tv". However, if I switch to TV display, and then play a video file, such as "mplayer movie.avi" , the tv screen goes crazy as if the scan setting is wrong.

The movie is displayed fine, though, if I play the movie before switching to TV. But again, the TV screen will go crazy if I stop the movie.

I'm suspecting this might have something to do with playing video files at low resolution since I started X at 640x480 for TV-out. When movie.avi is played (with mplayer,vlc) the window width and height are both bigger than needed and the picture is at the top left corner of the window. But as I mentioned earlier, if I switch to TV after playing the video, the picture is displayed fine on TV (without the extra width and height)

Thanks in advance for your help.

I guess I posted this question in the wrong section. This should be in the software one. Well, just in case somebody has similar problem with TV out, here's how I solved it. Instead of changing screen resolution from inside Ubuntu, I edited xorg.conf so that X starts in 640x480 resolution.
