Hopefully, still in the spirit of this thread ...

I'm trying to get a Nova-S card (w/o decoder) to work w/ mythtv (current 
CVS version). It works w/ xine, so I'm sure the card is delivering. 
 I've installed the MythChannels .10 patch and code as well at the 
current linuxtv 1.0.0 dvb drivers.  Mythtv works fine with my PVR350, 
although I started w/ a clean database for this test. I had a few 
problems initializing the database for a DVB-S card, though nothing that 
mysql couldn't fix. Once I get things working, I'll report in more detail.

The backend tunes the card and reports FE_HAS_LOCK.
Running Mythtv produces a blank screen and no console output other than 
a "connecting to backend..." msg.  Changing the use_ts flag (0 or 1) 
seems to make no difference.

The backend output is at the end of the post.

Any ideas?
