i have windows media 10 player and when ever i try to play a vid that is a mpg, i get an error report, and it wants to play as and audio file....right now i have all of the file types checked off. should i uncheck any? also this seemed to have started after i installed adobe premiere 6.5 which comes with an mpeg encoder. could this have messed with it? i unistalled and i still get the same problem
