Right, I got that.  And I think it is the correct approach since it preserves
maximum information.  However, I somehow had the idea that it would transcode
and scale as necessary near the output.  (In my defense, there is a lot of code
in MythTV proper and a rather large number of libraries.  It isn't immediately
obvious that it doesn't do this. :)

Sure, if it could I could just copy from /dev/dtv to /dev/video17.  A few
little scripts to make recordings and I wouldn't need MythTV at all... :)

I set this up on a 3.2GHz P4 machine with that in mind.  But it sounds like
what I want doesn't really fit the current MythTV infrastructure.  (By the
way, the *other* thing I want is FireWire/DV in/out which might present
similar problems.)  Since MythTV is already rather large and complicated
(and given the problems I'm having with the front end hanging) I'm not sure
whether starting from scratch might be more efficient than hacking the existing
