I take the silence as meaning that no one knows what I'm talking about...

Anyway, if anyone gets the DVB drivers working with the pcHDTV 3000 and
Myth, let me know.  I'll have a few questions on how you set up the
channels.  (Like "How do you set up the channels?").

YEAH!!!  I downloaded and installed FC4 and Myth liked my card with the DVB
drivers!!  (Thanks, Tom!) However, I still can't watch TV and I think it is
because of the channel settings.  I download only the "DT" channel listings
from zap2it.  They show up in the program guide, but don't show up in
MythTVSetup's Channel Editor.  I tried the Channel Scan, but it couldn't
find any signals to lock on to, but I know there is an OTA HD signal in my
area that I have viewing previous with xine.  I remember a message somewhere
about needing to modify the channel frequencies to get it to work, because
Zap2it doesn't include the right ones.  I just can't seem to find the note.
Anyone have any tips for tuning to the right channels on the pcHDTV 3000?

Installed FC4, followed Jarod Wilsons guide,  even tho its for FC3.  
Since FC4 is using a 2.12 kernel, all I needed to do as root was:

modprobe cx88-dvb

Checked dmesg and saw:
cx2388x dvb driver version 0.0.4 loaded
ACPI: PCI Interrupt 0000:01:07.2[A] -> Link [LNK1] -> GSI 3 (level, low) 
-> IRQ 3
cx88[0]/2: found at 0000:01:07.2, rev: 5, irq: 3, latency: 32, mmio: 
cx88[0]/2: cx2388x based dvb card
DVB: registering new adapter (cx88[0]).
DVB: registering frontend 1 (pcHDTV HD3000 HDTV)...

Checked the permissions on /dev/dvb/adapter1 (as adapter0 is my air2pc 
card) :
 ll -h /dev/dvb/adapter1/
total 0
crwxrwxrwx  1 root root 212, 68 Jul 23 11:44 demux0
crwxrwxrwx  1 root root 212, 69 Jul 23 11:44 dvr0
crwxrwxrwx  1 root root 212, 67 Jul 23 11:44 frontend0
crwxrwxrwx  1 root root 212, 71 Jul 23 11:44 net0

All was good on the permissions (note, you may need to modify the 
permissions on the dev if you dont have rw access to it, and it may not 
survive a reboot, so youll have to add it to your init scripts)

Fired up mythtv-setup and was able to config the pchdtv3k card with no 



P.S. Oh yeah, this is for OTA HD broadcasts and I CAN watch and record 
off the pchdtv3k card.
