Up until Just an hour ago i had no problems playing any movie file. Well i installd the drivers for my vid card so i could play the movies on my tv and all of a sudden whenever i play a vid file i canot get it to go over a certain size. it will start out playing normally but then will jump down to a smaller size. to see a screen cap of it go to www.awh.kicks-ass.net/WTF.gif that is a screen cap of the prob im having. (the cap is of both screens) no matter what i do i have not been able to get my full screen back. That pic is of the full screen and that is all i get. Oh btw the pic may take a sec to load (its kinda big) and the black around the movie is what i see on the screen. It is supposed to be in full screen mode at this point but this is as big as i can get it. Once again thanks for the help. I have uninstalled every codec and player on my pc other than win media player. If i try to play some files now i get an error that it was unable to decompress or that it is an invalid file format. If i install the the XviD codes and the AC3 audio decoder i get the same problem as before. (the small screen) All files that do play without these codecs installed will play fine and will maximaze to full screen now without a problem. So it seems as if i have narrowed it down to those 2 codecs the XviD and the AC3.
