whenever i download video files from torrent sites, the output, if played with vlc will show a slanted green line cutting through the screen. this happened with a few of the movies downloaded from different sites. i use transmission. any thoughts why this is so? i tried playing with other players, okay naman but there's always some other problem. i always thought vlc is the best, so i don't use other players. any thoughts why this happens if i play them in vlc?
