Hi Kyle,

Everything seems to be working fine, except for a couple of things. It's
been running for four or five days and hasn't stopped yet. It's making
two files, the m2v is almost 5 gigabytes now and the ac3 is about 9 gig.
Somehow I don't think it's working right. Googling for transcode spells
and also looking at the manpage, I don't see anything overtly wrong with
the command line. In the VIDEO_TS directory I have four VOB files and
two IFO files. I just ripped the main movie, not the menus or extras.

I've pasted the output from transcode at the end of this email.

Any hints?

Thanks,

Bob
