Comment 5 for bug 281436

Found a sollution, this bug is sitting here way to long, ok here's what i did :
Install the following packages:

libavcodec-unstripped-51
libavformat-unstripped-52

Might need both might need one of these, either way i have installed this and now motion works.

Please note that these are multiverse packages and i dont know how it impacts the rest of the packages maintained by ubuntu, because this removes the stripped versions as they conflict with each other.

Please let me know if it did the trick for you to :)

Greetings Jan
