ffplay (SVN from 31-1-2009)has choppy playback with rv30 and rv40 video, its
especialy noticeable in slow moving paning scenes. It looks very odd, could be a
timing issue but im not shure. 
If someone could take a look at this ?

Cpu is Athlton 64 Tk-53 x2 @ 1.8 Ghz Vista 32bit 2gigs mem cpu usage is around 20 to 25 % while playing
The stuttering might not be noticable by a casual glance but it certainly is there,
could it be that the realplayer dlls do some kind of frame interpolation ?

here a snipet of the file
