BUG: v1.03 Video plays fast then pauses

Hello I have several media files where the video plays a little fast for a
few seconds, then pauses while the audio catches up. They're mencoder divx
files in AVI. I found that the problem was the wdtv not properly handling
that duplicate frames omitted during encoding. (they play fine in mplayer)
I found I could reproduce or solve the problem by omitting or specifying
mencoder option harddup.
Here is the mediainfo for one with the problem. I compared it to another I
recently encoded and besides the program/library versions being different,
I noticed that the video is slightly shorter than the audio here, while
strangely the other has audio much much longer, like double. But like I said,
mplayer plays the files perfectly.
thanks
