OK, so I think I figured out part of the problem. In the mythfrontend
setup screens under hardware decoding settings I had checked several
times to make sure I had the PVR-350 decoder marked. However, since
adding the new card the PVR-350 comes up as video1 not video0 as it did
before. I still have video16 set for the encoder output. I realized
this after finding a multi megabyte file under /dev named video16.
Guessing that this output was increased by one I changed that value to
video17 and now I have smoother video output and sound going out the
PVR-350 card once again.
But now I am still getting this error when trying to record two shows at
the same time:
error reading from: /dev/video0
read: Device or resource busy
I found one thread where the the same minor numbers were set on the
device files but that is not the case with my system.
lrwxrwxrwx 1 root root 6 Mar 24 14:30 /dev/video -> video0

Is there something in the database that needs to be changed to get the
second card working?

Not enough sand.
