1. Confusing is an understatment. Forget about support response. I 
actually ported some code for them to get dtvsignal to work with v4l2. You 
want the drivers under downloads and the name is : 
HD3000-HD2000-CD-rev3.tar.gz(11/19/04 ) 

2. It does show 3. I only have 2

3. I always install the cx8800 drivers last. So get ivtv installed (not 
loaded) and then I make sure no modules are loaded:

rmmod btcx-risc.ko
rmmod bttv.ko
rmmod cx8800.ko
rmmod cx88xx.ko
rmmod tuner.ko
rmmod v4l1-compat.ko
rmmod v4l2-common.ko
rmmod video-buf.ko

and then I remove all instances of the modules:

find /lib/modules -name btcx-risc.ko -exec rm {} \;
find /lib/modules -name bttv.ko -exec rm {} \;
find /lib/modules -name cx8800.ko -exec rm {} \;
find /lib/modules -name cx88xx.ko -exec rm {} \;
find /lib/modules -name tuner.ko -exec rm {} \;
find /lib/modules -name v4l1-compat.ko -exec rm {} \;
find /lib/modules -name v4l2-common.ko -exec rm {} \;
find /lib/modules -name video-buf.ko -exec rm {} \;

Then I make sure the drivers in the cx8800 directory are remade:
rm *o
make install

After the make install you should see that the cx8800 driver loades with 
no problems (check dmesg)
Then load the ivtv drivers.

I assume your card shows up in lspci?

Would you be able to give a bit more information on
how you got your PVR/PCHDTV combination to work?

First, the pcHDTV website is confusing.
Which download?
Under the bullet 'Full Upgraded Software?
Or under the bullet 'Latest V4L-hd Driver?

You say you have 2 PVR250s, yet the modules.conf
shows entries for 3, doesn't it?  (Mine is called modprobe.conf.)

It would help a lot to know the list of modules related
to the PCHDTV driver that have to be deleted, especially
since it seems to me that some of the IVTV modules have
the same name(s) as the PCHDTV modules.  It is SO hard
to figure out which software to install, I have never gotten
past that point.

I don't even look at the HD-3000 boxes anymore because
I just get so depressed reading about how others have got
their machines recording HDTV, and I can't figure out how to
clean up the mess I've made trying to install the PCHDTV
software.  Jarod's HOWTO has just made it too easy to get
something working without knowing what I'm doing. 

OH - how I wish there were a HOWTO such as Jarod's
for the PVR/PCHDTV combinations, specifically a PVR-350
with one or more HD-3000s.

Thanks, if you can provide any more information about
what you did to get your combination working.
