Now I did the following: Removal of all ffmpeg-versions (see above) and libavcodec/util/-dev, which included searching for them manually to be really sure everything's clean. Afterwards I reinstalled to result in: root@linux:/# dpkg -l libav* |grep ii ii libavc1394-0 0.5.1-1 control IEEE 1394 audio/video devices ii libavcodeccvs 20051016-0.1 library to encode decode multimedia streams ii libavcodeccvs-dev 20051016-0.1 library to encode decode multimedia streams ii libavutilcvs-dev 20051016-0.1 avutil devel files ii libavutilcvs0 20051016-0.1 avutil shared libraries root@linux:/# dpkg -l ffmpeg* |grep ii ii ffmpeg 20051016-0.1 audio/video encoder, streaming server & audio/video file converter root@linux:/# Nothing more, nothing less. Debian installs ffmpeg to /usr/include/ffmpeg, thus I changed dxr3-plugins' Makefile variable FFMDIR to mach this. make clean, make plugins in vdr-1.3.31/ compiled the dxr3-plugin new, and now everything works fine, thanks so much!!! I spend ages working on that problem, that did it! Ok, one tiny problem is still left - sound and video have a little delay, they are not fully synchronous. Sound is a little ahead, I would say about half a second - not really s.th. to worry about, but enough to be annoyed :-) Is there some known solution to this too? Again - thanks so much for helping! Glad regards, Andre
