Hi:  I was glad to see Paul's technique because I have been trying to 
copy VHS to DVD too.  When I tried just recording from live TV the 
recording stopped on the next half-hour, and I went instead to the 
Manual Schedule, which wanted a preset duration.  I've looked for a 
'Record Continuously Until Stopped' setting but haven't found one yet.

I have also had difficulty with some recordings in getting useful 
quality settings, and in getting Mytharchive to complete.   Nuvexport 
did a good job on some of them, but has apparently ignored quality 
settings on others.  Some of the files have been through several 
experimental sequences so it's difficult to pin down the real problem. 
My capture device is an saa7134, so the initial Myth output is in .nuv
