I disagree since I have two DVB cards (air2pc hd5000 and KWorld ATSC110) that both experience this problem. They fail with this error to the point where they are useless.  I can use MythTV but only for SD using an old BT878 card (not HD or ATSC).  My SD OTA reception is not very clear so I'm eager to move to ATSC recordings.

The bug is in SVN revision 12619, so there is something in that code, 
versus 12618 that causes the problem. I believe this was the 'quicktune' 
feature. The developers of the HD Homerun (which I am using) say that 
top of trunk now works for them, so I may setup a test backend to see if 
it does in fact work.

Otherwise, stay with 12618 until ticket 3031 is fixed.
