pvr250 can't tune above channel 11

Newest rev of pvr250 driver says:

   cxm0: <Conexant iTVC16 MPEG Coder> mem 0xe000000

   cxm0: [GIANT-LOCKED]
   cxm0: encoder firmware version 0x2040024


When I run pvr250-setchannel with a channel number above 11, it says:

   /usr/ports/multimedia/pvr250 >pvr250-setchannel 12
   ioctl( tfd, TVTUNER_SETCHNL ) failed.: Invalid argument

and /var/log/messages says:

   cxm0: video decoder failed to lock
   cxm0: audio decoder failed to lock

Channel numbers 11 and below work just fine.  Recorded some pretty nice 
looking mpegs.  This is with over-the-air TV (us-broadcast).

Any ideas?  Thanks.
