I have a DC30 (ZR36057) which fails to record with lavrec. I've booted grub with mem=2030m (out of 2048), modprobed with this line - modprobe zr36067 v4l_bufsize=512 card=3 v4l_nbufs=32 Tried card=4, also tried no option on modprobe, and no grub options. The module is loaded at boot time. The card is on it's own IRQ, verified to work in other PCs (and this one) with WindowsMe, 2000, and XP. Xawtv does display the input image on overlay, but nothing else.
