Re: Tcrequant breakthrough!

For some reason vamps doesn't properly work for me, uses up lots of cpu
cycles (and if running with -v -v produces output) but it just seems to
stop producing output at some point and never actually completes...

My guess is that it sees something in the input stream which causes a problem,
as it always stops at the same byte count on a given file.
