I downloaded a completed .avi file from a P2P program, but when i try to play it on Divx Player, it shows an error msg about the file, on WMPlayer, it shows a msg askin me to restart it n send a report to their company, RealOne Player also shows an error msg followed by an error on "MMSWITCH.AX". I already downloaded tons of codecs to make it work but it doesnt. i also re-downloaded the file, but it still wont work. The only program that the file worked on was in VirtualDub. I dont like using this over n over because the video lags at one point n i cant make it play in fullscreen. So please help me. I really dont know what to do next.
