nxt200x is a dvb frontend driver -- it is NOT a tuner driver, although
it does work with the tuner, but not on your board (pchdtv 3000).
nxt200x is used by cx88-dvb for the ATi HDTV Wonder, and it's used by
saa7134-dvb for the AVerTVHD A180. The nxt200x was not present in
2.6.14, although it IS present in 2.6.15 and v4l-dvb cvs. We know that
this is not causing your trouble because Kirk Lapray has both the ATI
HDTV Wonder AND pcHDTV 3000 installed on his system, and he says both
are working properly.

However, I don't know if Kirk has tried 2.6.15-rc3 yet...

Kirk, do both cards work properly in both analog AND digital video?
...or were you only talking about digital? Kirk, I could really use
your help in diagnosing the problem that Gene, Perry and Don are talking
about. It looks like something in the 2.6.15 patchsets broke analog
video on the pcHDTV 3000.... Would you kindly be able to test 2.6.15-rc3
on your hardware?

Gene, Perry and Don -

I wish that we could resolve this with a -git bisection test...
Unfortunately, we cannot do it this time, as the VM_RESERVED memory
problems existed throughout 2.6.15 development.

All I can think of doing is telling you to start reverting cx88 / tuner
related v4l patches, but that is very tedious....

Another idea is to try installing cvs again on top of your kernel, but
with each unsuccessful checkout, back out cvs a few days, using the -D
option.....

If you need better details on how to do this, let me know... I'll try to
write something up.
