You (everyone) should definitely be running with --dd-grab-all, assuming 
your system isn't underpowered.  See the posts I linked.  If you always 
do, it would have made things easier for both you and SD/TMS systems.

That said, I'm glad you have it working.  I'd still check for any other 
MythTV channels with the same XMLTV ID, though.  It may save you 
problems later if it's just a race between 2 channels determining which 
gets the data (and will prevent huge inefficiencies (and potential 
problems) if you don't change to using --dd-grab-all).
