I generally agree that the DVB drivers do work with the HD3000, but they
are not 100% reliable compared to the 'official' pcHDTV drivers.

Comments I have on the DVB drivers with HD3000 in MythTv (in the US):
- Guide data integration is not as plug-and-play as it is with the pcHDTV
drivers because the DVB drivers don't use the same numbering convention as
we are used to in the US.  You have to utilize the myth setup channel
scanning feature to add channels.  Some creativity is needed to map the
guide data to the DVB channels.
- Scanning for and adding ATSC channels is a bit cumbersome (lots of menus
to go through - channel scan freezes sometimes)
- I left the PC on the same channel overnight, and the next day the
channel was all garbled (exiting live tv and entering it again fixed the
- SNR (signal noise ratio) values are buggy (they don't start at 0%)

I originally tried out the DVB drivers because I was having lock-up
problems with MythTV, but I found out that the driver wasn't causing the
lock-ups.  After experiencing the reliability issues with DVB drivers, I
reverted back to the official pchdtv drivers.  YMMV

I also don't need QAM since I'm only using OTA ATSC, so I can wait a while
before making the DVB plunge.
