Me again lol...

For some reason, movies played in WMP are now running slow... Like, they stop, then quickly catch up, then it acts all jumpy...

It happens on all videos, even ones that were fine before the Vista upgrade...

What format are they in and what codec are you using?

A) Any format

B) To be honest, I'm not sure lol. Since Vista, I've had to re-install most programs and drivers so what would you suggest?

Is there heavy hard disk activity during this?

hey man,

I had encountered a similar problem in XP when I was watching a movie (any format just like you) and doing some other thing that was taxing on my video card (I enjoyed my fantasy of playing Doom 3 on my external monitor while watching CSI on my notebooks screen). What basically happened in my case was that the Video card wasnt able to keep up with everything, and so the video slows down, realizes it has done so, and then catches up quickly to re-synchronize with the consistent audio. In windows Vista this may be the case simply because vista inherently uses more graphics memory than XP does. You may want to try turning Aero off (if you have it on) or changing your preformance/appearance options to increase preformance. I doubt it has anything to do with WMP or codecs.

I have similar problem, but it appears together with poor quality (lowered resolution in movies i think and with bad colors)....

I think that solution to this problem can solve mine as well..

"SYMPTOMS

When you configure the video functionality to use interlaced mode on a Windows Vista-based computer, you may experience poor video quality. Specifically, the video output may be very jerky. You may also notice many dropped frames."

Microsoft have done a patch for it here : http://www.microsoft.com/downloads/details...;displaylang=en

this is not a driver problem at all but most likely a codec problem. vista's WMP just sucks in my opinion. whenever i watch a movie encoded in divx, the video will eventually fall behind the audio or things get messed up some other way.

b/c of those issues, i use vlc media player
