What else can i try? Obviously I don't know everything, or I'd know how to fix my own lockup problems! :-)
Some other things that I have observed and/or tried: 1. What chipset is on your motherboard? If it's a Via chipset, try a motherboard with an NVidia or Intel chipset. I've experienced problems even with relatively recent Via chipsets (eg., PT880 Ultra) 2. You could try maxing out buffers by adding this: "options ivtv enc_mpg_buffers=16" to /etc/modprobe.conf or your equivalent. Since you only have one card, that probably won't give you kernel memory problems. If it does, you may have to make some changes to your grub stanza. First, before the "kernel" line, add "uppermem 524288". Then add "vmalloc=192m" to the "kernel" line as a kernel parameter. 3. Try also adding "elevator=deadline" as a kernel parameter. Some sources claim it provides better i/o performance than cfq for this purpose.
