Ugh. You may have a point here.

I am not using the analog part of my HVR-1300 card anymore, so I don't
have those profiles at hand, but I remember having those problems and
solving them in that way when at first I wanted to get the analog part
working. I gave up and then we got the DTV amplifiers at my building,
and forgot about trying to get both the analog and the digital parts

I know that MythTV stores different profiles for DVB encoders and for
other types of tuners. If you happen to have two cards with hardware
MPEG encoders integrated (the pvr 350 and the MPEG TV Expert) and
MythTV creates only one group for both of them, I fear you might have
a problem if both of them require incompatible settings.

I'm sorry I don't know enough about MythTV to be of more help.
