I've been mostly running my system with one of the cards not configured in the system for Myth.
I recently added it in and now when the system records 2 shows, it seems to record one card's channels just fine (I think) while the other show is a blocky mess of broken audio. I wasn't watching TV while these recorded.
My System is a Pentium 4 HT (3GHz) with 2GB of memory.
nVidia GeForce FX5200
(3) HDisks, sda=300GB, sdb=250GB, sdc=250GB, sdd=dvd-rom
01:00.0 VGA compatible controller: nVidia Corporation NV34 [GeForce FX 5200] (rev a1)

I do have UDEV set to assign the cards to the same /dev/ locations every time.
I'm wondering if this system is too slow to record 2 HDtv streams. (they are OTA stations in HD over comcast cable)
Hard disk bog? CPU Slog? Video Card Conflict?
What's a good test besides just setting up to record two shows and watching "top"?
