No. This is a known limitation of the AVI format. Typically AVI's
greater than 2GB aren't "indexed" (though there are hacked
version of the AVI format which overcome this). You can stream
the AVI but you can't seek in it, necessary for editing.
A workaround would probably be to have mplayer reencode the video
to the smaller target size first *then* edit out the commercials.
But I suspect you're using mjpegtools. mjpegtools can record to
segmented AVIs. Why not use that option? Then you can run
something "glav movie-00*". Nowadays I use mplayer to record
straight to high-quality divx.
