[mythtv-users] Still have Black Screen with hd-2000

OK, I have made some progress.
I previously had both a hd-2000 and a PVR-250 in the box (Intel 3.2GHz,
Fedora2), and I never saw ANY signs of life from the hd-2000 but the PVR-250
worked fine.

I Pulled the PVR-250, and vola, the hd-2000 showed signs of life.

I can now do a dtvscan and see all the live channels I would expect in this
area (Albuquerque, NM) and doing a dtvsignal shows signal strength in the
85%+ range... Not too unexpected with all the signals coming from transmitters
on the top of the mountain about 6mi away, line of sight.

OK, as noted, dtvscan and dtvsignal show good stuff, but mythtv still shows
nothing, just a black screen, and I cant hit the 'M' key and get the index
up, nor can I hit numbers and see a channel I want to switch to ...
I SHOULD be tuning to a live ATSC channel by default, but who knows.

In the messages written to the window behind mythfrontend, I see the following
messages, which are probably significant:

    2004-12-20 12:52:40.536 Changing from None to WatchingLiveTV
    2004-12-20 12:52:48.199 Maximum signal strength detected: 13% after 5500 
msec wait
    2004-12-20 12:52:48.199 Signal level too low?
    2004-12-20 12:52:48.199 Tuning Error -- aborting recording
    2004-12-20 12:52:48.199 TVRec: Recording Prematurely Stopped

This is saying that there is a tuning error and the signal strength is 13%
rather than the 85+% that I see with dtvsignal.

So, Im running kernel 2.6.9 with the
    kraxel v4l2 patch:	All-2.6.9-rc4.diff.gz
and the pcHDTV patch

Have I missed something???
All the other patches Ive looked at seem to have made it into 2.6.9 (final).
