||MythTV not talking to PCHDTV 5500 Cards

|Here is my system configuration:
Intel DQ965GF Micro ATX Motherboard
Intel Core2Duo E6600 2.4GHz CPU
2x1G Mushkin DDR2 800 (PC2 6400) RAM
XFX GeForce 7600GS 256MB PCIExpress16 Video Card
2x PCHDTV 5500 Capture Cards
WD Caviar 1TB 5400 to 7200 RPM SATA 3.0 Hard Drive
ASUS 18X DVD+-R SATA DVD Burner w/LightScribe
Antec Veris Fusion 430W Silver HTCP Case
Turtle Beach Audio Advantage SRM USB Sound Card
Fedora Core 8 (x86_64)
100MB ext3 /boot
16GB ext3 /
950GB xfs /storage
NVidia Linux Drivers v100.14.19 (Installed from NVidia)
ALSA Sound Driver v1.0.15: USB Audio (Installed by FC8 DVD)
MythTV v0.20.2 (Installed via RPM)
Configured with MySQL
Schedules Direct account active
I've been following the Installing MythTV on FC7 document as that appears to be the most recent document and so far anything different in FC8 has sort of automatically made itself known.
The problem I am having is that I can't get the MythTV system to talk to the PCHDTV 5500 cards. I know the cards are at least partially working because I can use TV time to tune cable (though without any sound for some reason). I know that the rest of the MythTV system is at least partially functional because I've managed to get it to playback mpg2 and divx files through the Media browser on the MythFrontEnd (with sound).
Part of the problem may be related to settings. There are an awful lot of settings that, at this point in my learning curve, are completely meaningless to me. So, I leave them alone.
I have Cox Cable, with the digital cable and HD cable activated. I have used a splitter at the wall to send one signal to each of the PCHDTV 5500 cards and one signal to the cable box. I have set the card to NTSC, US-Cable, QAM256 (which is what I think are the right settings) and attempted to scan for channels. I get no signal on any channel. I've also tried a few of the other settings, but nothing has worked. Now I expected a hard time on the HD cable channels, but not on the basic cable stuff.
I downloaded ATSC scan and got these results, which told me the cards themselves can see something, though I don't know how useful any of that information is:
My goal is to be able to record all the channels that my provider offers in the clear, whether they be standard def or high def. I've been hoping to find some information that says, Hey these are the optimal settings, but as is more often with Linux, I have not. So I'm hoping someone can help point me in the right direction, because at this point I'm not even really sure what to do next.
Thanks for reading,

|Well I've solved most of my problems thanks to help from here and the mythtv mailing list. I still have a ways to go, but for those who are interested:
I had to change to the DVB settings for the capture card instead of the pcHDTV settings. This allowed me to scan for HD channels.
I originally used the analog settings in the DVB to try and get SD cable working, but that only got me video. In the end, I had to create 2 separate tuners for SD under the V4L settings. I still get some noisy static when I change channels occasionally, but that's a minor problem compared to having no sound at all.
Oh, and the other big change I had to make was to revert to the 100.14.11 NVidia drivers. The newer ones are buggy and don't handle the transition from video playback types. The older drivers don't play well with FC8, but there's a fix for that out there.
I still have plenty of work left to get everything tweaked just right, but I wanted to thank everyone who offered their help.
