I have noticed smilar trouble:
When VDR playbacks a recording, and I pause playback and put play
again, video starts playing, then stops for less than second after about 5
seconds, then plays, after two seconds stops again for one second, and
then plays smoothly.
I have noticed "replay stuttering" trouble sometimes, but increasing
PLAYERBUFSIZE to MEGABYTE(8) resolved the trouble.
