is this a problem on osx ??

even real player mac can't run it 100%.


i played the same file on both windows and mac, windows play it better.


when playing on osx it have many lags (when the picture move slowly).
 
I got a similar problem if the video files are on a network drive. I use VLC to play the file.
 
What specific Mac do you have and what settings does the .rmvb file use?
You can use VideoSpec (I prefer that, though it hasn't been updated since 11/2009), MediaInfo Mac (10/2010) or MediaInfo (10/2010, there is a Mac OS X version to download, VideoSpec and MediaInfo Mac are using the same library as MediaInfo) to analyse the .rmvb files.

i have 2.53 GHz intel C2D with 4 GB (late 2008 MBP )

I tried that video and it doesn't play fluently in VLC for me too, but it is not CPU intensive, VLC stays around 20% on a 2GHz C2D CPU.
MPlayer OS X Extended does the same.
RealPlayerSP seems a bit better, but the audio is not in synch.

Seems that file is not properly transcoded. Maybe you need to find another source or format for that video.

yeah i think so because these files transcoded with subtitles.

and i convert all these videos to avi and then played them in movist.

the lags are less in avi.
