I tested everything you guys suggested, and ended up booting into older
kernel-versions. I finally found a kernel-version that returned a
suxxesful grab. After this i did a diff on the kernel-config-files, and
found what was missing from my new configs: CONFIG_VIDEO_V4L1_COMPAT=y
(Device Drivers->Multimedia support-> Enable Video For Linux API 1
Enabling this, recompiling the kernel, replacing the kernel-image and
rebooting my vdr returned the grab-feature of vdr!!
I'm not sure why vdr 1.6.0-2 needs this setting, but anyway this solved
I hope that if someone has similar problems, that these instructions
help them getting grab to work again!
Best Regards, and have a merry New Year 2010 :-)
