A couple of observations, but I'm not sure if any of these explain why
your PC crashes:

1. vidrate is supposed to set the bitrate for the video encoding.  For VHS
quality, this would be around 1000000 (1 million) bits/second.  You can
look at http://www.bernclare.com/encoders.htm#Q2 to get some ideas about
how high to set vidrate.

2. I don't think you can set VBR via the commandline right now.  From
looking at kfir.c, VBR is automatically selected for MPEG-2 (and likewise
CBR is set for MPEG-1).
