I tired the script Reverse.AVISOURCE("myfile") in Vdub but the output video was very slow.

Can I get a different way to do it.. thanks

Video compression is optimized for playing the video in forward direction. For example P-Frames code only the difference to the previous frame.
Accessing the frames in reverse order is slow for obvious reasons: It is necessary the decode a lot of frames in normal order, to get the first frame in reverse order.
If you didn't cache all the frames in between, you may need to do the same procedure again to get the second frame in reverse order. And so on...

yup

Try reencode you avi file to other avi file with lossless codec with only intraframe and rverse will be work faster.
yup.
