hmm, yes you are, but I can't reproduce that failure:

$ which oggz-chop
/home/conrad/usr/bin/oggz-chop
$ oggz-chop -v
oggz-chop version 0.9.9
$ rm yt1.ogv
$ oggz-chop -o yt1.ogv -s 0 -e 500 ondrej.ogv
$ ls -l yt1.ogv
-rw-r--r-- 1 conrad conrad 59548832 2009-06-17 11:17 yt1.ogv

can you help with debugging to see where it is failing on your system?

Conrad.
