When i start to play most movies (mostly divx and xvid encoded ones) my computer comes to a grinding halt for a minute or so until the movie starts to play....no hard drive activity is going on at this time, it just sits there, i cannot move my mouse or anything. Once the playback starts all seems well. Running xp pro on an athlon xp2100 with geforce ti4200 and detonator 45.23's soltek nforce2 mobo. Previously i had no problems such as this then they started. I formatted and reinstalled everything clean on a new hard drive and the problem continues. WMP sits saying "opening media...... or connecting" Non encoded movies, such as video clips taken with my canon digital camera play fine with no hesitation. Im using the same codecs i always have, xvid, divx5 and ac3 installed on a clean format. ANY help is appreciated, thanks.
