I didn't get any suggestions when I posted this a couple of weeks ago so I thought I'd try one more time.
I have a new PVR I've built with a single PVR-500 installed. Everything seems to work when accessing the first encoder. However when I test the second encoder with 'cat /dev/video1 > test.mpg' the host will lock-up after I hit cntrl-C to stop the capture. I've tested this both with the tuner and with the second S-video input on the second encoder. After rebooting, the test.mpg file is fine -- the stream was encoded correctly. I found http://www.mythtv.org/wiki/index.php/PCI_Latency on the MythTV wiki but I don't seem to be able to reset the latency on my SATA controller. After running the command listed there, my latency is still zero: 00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) Serial ATA Storage Controller IDE (rev 01) (prog-if 80 [Master]) Subsystem: Elitegroup Computer Systems Unknown device 1b76 Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 201 I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at fb00 [size=16] Capabilities: <access denied> Could the second encoder sharing an interrupt with the NIC be the problem? $ cat /proc/interrupts CPU0 CPU1 0: 32333565 32310269 IO-APIC-edge timer 7: 0 0 IO-APIC-edge parport0 8: 0 0 IO-APIC-edge rtc 9: 0 0 IO-APIC-level acpi 14: 43664 32798 IO-APIC-edge libata 15: 672694 717319 IO-APIC-edge libata 169: 2140359 2267566 IO-APIC-level uhci_hcd:usb4, HDA Intel, nvidia 193: 1764223 1872627 IO-APIC-level uhci_hcd:usb1, ehci_hcd:usb5 201: 86629 103848 IO-APIC-level uhci_hcd:usb2, ivtv0 209: 0 0 IO-APIC-level uhci_hcd:usb3 217: 4197437 0 IO-APIC-level ivtv1, eth0 NMI: 1771 1037 LOC: 64630644 64630571 ERR: 0 MIS: 0 I'm using the 0.10.5 driver from ATRPMS on CentOS 5 x86_64.
