Ah, OK, thanks for checking. One reason why I was using chapter mode was 
that transcode would exit if I used the standard -o flag sometime around 
the and of the first chapter (on some discs, not all). This only seems 
to happen when ripping direct from the disc - if I use vobcopy to copy 
it then it seems OK, but I prefer to rip straight from the disk as my 
hard disk always seems to be almost full ;-)

Another question: Can I use the log file from the first pass of a 
two-pass encoding but change the target bitrate (-w) in the second pass?

thanks
