When i watch videos on windows media player the video lags (not too bad but a little bit). I play oblivion and it doesn't lag. Why is it lagging when playing a mere video. Isn't my video card supposed to play that without any problems at all?

i didn't have that problem before. Thanks for any help

might be some codec issues, im sorting some out on my media center as i type [vista 64 is a PITA for codecs, and drivers]

what type of video?

 

[dude_se]

yea possibly codecs. tbh ive said it before and ill say it again. "vlc" it the best for videos

ya vlc supports almost all codes and for the ones it doesn't you can probably find a plug in somewhere
