So when I had Visa, all my Mkv, avi files played widescreen. Black bards on bottom and top. Yeah..you know. I liked it. But now when I have windows 7, each of my players play my videos full screen, like a square box that stretches when I go full screen. I use VLC or Media player classic. I ratther use media player classic because it plays mkv files in better quality. So my question is, anybody know whats the problem? I'm asking for help, to see how can I play my videos in widescreen again.
