At least you guys can get those channels to tune.  I can't get it to
lock properly and find the dummy video (NA) at all -- it says:

2007-01-08 16:42:21.353 DTVSM(1) Error: We want 0 audio and 1 video
                        But have 1 audio and 0 video streams

I tried setting the video PID to 0x200 and changing the dimensions of
the video to match this file dummy1280x720p25.00.ts.

Not sure how to debug this one...
