OK, I swapped my PVR-150 with my wireless NIC, just to give it a try. I recorded with the PVR-350, still looks great, and recording with the PVR-150 still has OK sound, jumbled picture. Here is the new lspci output: 00:00.0 Host bridge: Intel Corporation 82850 850 (Tehama) Chipset Host Bridge (MCH) (rev 02) 00:01.0 PCI bridge: Intel Corporation 82850 850 (Tehama) Chipset AGP Bridge (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 02) 00:1f.0 ISA bridge: Intel Corporation 82801BA ISA Bridge (LPC) (rev 02) 00:1f.1 IDE interface: Intel Corporation 82801BA IDE U100 (rev 02) 00:1f.2 USB Controller: Intel Corporation 82801BA/BAM USB (Hub #1) (rev 02) 00:1f.3 SMBus: Intel Corporation 82801BA/BAM SMBus (rev 02) 00:1f.4 USB Controller: Intel Corporation 82801BA/BAM USB (Hub #2) (rev 02) 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R100 QD [Radeon 7200] 02:07.0 Multimedia video controller: Internext Compression Inc iTVC15 MPEG-2 Encoder (rev 01) 02:08.0 Mass storage controller: Promise Technology, Inc.

Again, I don't think this is as important as the correct settings in /etc/mythtv/modules/ivtv. Does anyone have a similar setup (for two PVR-x50 cards) they could share?
