Skipping during movie playback, driving me mad please help

[atconc]

I'm having problems with playback of Divx and Xvid movies. At random intervals the movie either skips forwards or skips backwards what I would guess must be a few frames(affecting the picture and audio). I don't think the files are corrupt because the skipping can occur at different points in the same file seemingly at random (ie you play the movie twice, one time it skips at point x but plays fine at point y another time it doesn't skip at point x but does at point y

At first I thought it might be a problem with my disk, but the same thing happens streaming movies over the network.

I thought it could be graphics drivers but the problem happens on both my displays.

I also thought it could be a codec issue, but it happens with both divx and Xvid. All the files do seem to have MP3 audio, but I don't know how to change the audio codec. Since building this system I have also had problems with stuttering MP3 playback, but this was cured by a winamp update. I also tried installing ffdshow, reinstalling direct x9, disabling windows indexing service and installing the latest via hyperon 4 in 1 drivers.

The problem seems to occur regardless of what or if any other programs are running in the background, I've tried watching the cpu monitor of taskmanager while the movie plays and wmp is only using less than 50% cpu and cpu activity seems to drop a little when the skips occur.

I've been trying to figure out what I else I can try to fix it or track down what's causing the problem, any suggestions will be greatfully recieved

"Playing the movies in WMP 9"

There have been tons of complaints about the performance of WMP9.

I'd suggest you try using good ol' reliable Windows Media Player v.6.4. Install it as follows:


Desktop>>Start>>Run Then type MPLAYER2.EXE

Reboot

it turned out to be a problem with my soundcard, I cured it by reducing the hardware acceleration slider in advanced settings, but it was causing games to crash too so I ended up replacing it

Glad to hear you've resolved your dilemma ;>}
