xvcd w/ mpeg1 vbr can't ff/rw in wmp

[JHebert]

I have been experimenting with making a dvd rip to xvcd using mpeg-1 with 2-pass vbr at 23.976fps. The settings were 352x240 with 1700 average, 500 minimum, 2500 max bitrate. I am using a modified ntscfilm template in tmpgenc. The movie is animal house and is about 98% progressive according to dvd2avi.
The resulting mpeg plays fine in windows media player with good quality video. The problem is it won't fast forward or rewind correctly. If I drag the slider to jump to a different point in the movie, it freezes on wherever I set the slider and displays only a still image, as if I had paused the movie. However, the playback counter still continues as if the movie were still playing. Sometimes it resumes playing after a delay of over a minute. I haven't yet burned it to vcd to try in my dvd player (rca5240p).
I first thought it might be a problem with the framerate, but I have done xvcd with ntscfilm template before using cbr and they work fine. Maybe the 2-pass vbr is the problem.
I also tried demuxing and running the video through mpeg sequence maker and then remuxing, but this had no effect.
Anyone have this problem before and have some advice? Do you think it is just a problem in media player and that ff/rw will work in my dvd player?

It does the same for me too. I have no clue why. I would bet its a WMP thing. I have made test files with the same setings. How does it look on a TV?

Well I finally made an XVCD and it plays great in my RCA5240P DVD player. FF/RW work correctly and the quality is definitely better than CBR bitrate XVCDs I've made before using the same bitrate as the VBR average bitrate I used on this one.
By the way it also played fine in PowerDVD on my PC.
I guess the problem was just with Windows Media Player. I noticed that VBR MPEG2 files also have the same problem.
