I'm re-sending this because the original had the wrong From address, sorry:)

That fixed it.  I can now tune my dss tuner to any channel except the
"local" channels (upper 800s) but that's an XMLTV issue or a problem with
the data source.  I did run into 2 new issues however (actually 1 new and 1
old that I had forgotten about).

1.  The cvs version exits with the error "Illegal Instruction" if I have
deinterlacing turned on in the settings.txt.

2.  mythfilldatabase starts fetching beginning with tommorows data rather
than todays.

I'm planning on taking a shot at it but I'm not much of a programmer aside
from the occasional script.  I've also mentioned MythTV on the marvel-linux
and mjpeg-user mail lists so maybe someone there will take an interest.  One
of the folks on the marvel list has a patched version of ffmpeg that uses the
Marvel's mjpeg hardware so maybe a look at his changes would help.
