I just got it running with Mythtv, so I'll have to watch for that. > > Qs relating to the Plextor unit. > > 1) Quality is real nice, but the file sizes are almost as big as the > > MPEGs from the 250 board!

I'll have to check. If I remember, it was set at 2200 by default.

Poking around this morning, I notice that my nuvexport problem may be nuvexport itself. It doesn't even want to handle the files from the -250 board. Even debug shows nothing.
