I have had problems in getting screen captures from VDR (VDR 1.6.0_p2-r3 on Gentoo) with with for example:

check your plugins, most plugins can block the device like the avards-plugin
Hi Thomas!
This sounds interesting! Never heard about this before.. Is there any way to check which plugins might block the device, or do I just have to start by disabling all, and going through each plugin one-by one?
yes, this is the best way to find it. Just start with no plugin.. when it is possible to grab the image, than one of your plugins block the device. (this is also what I did for a while: http://www.vdr-portal.de/board/thread.php?postid=809751#post809751)
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 compatible Layer=y)
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 the case.
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 :-)
