Thanks for all the info!  I suspect I'll just use mythweb but I'll look into
mythexport too.

Somewhat OT but how does myth decide whether to record as *.mpg or *.nuv?  I
just checked my (nearly all SD) BE and I only found a single *.nuv file that
was very small.  Is this set in the recording profiles or SD vs HD?

thanks in advance,
