Well, I don't know what fixed it, but I now have good playback _and_ ffmpeg works via yuv4mpeg stream! Woohoo!
The last few things I changed for the record: 1) downgrading to the version of ffmpeg in the ubuntu repository. This was version 3:0.cvs20070307-5ubuntu7.1+medibuntu1 2) reinstalled everything I had installed via akirad repository. These are: akirad-keyring-and-mirrors, akiradnews, cinelerracv-gl, libgavl1, libguicastcv-gl, libmpeg3cv-gl, libquicktimecv-gl, optlibx11-noxcb-6, optlibx11-noxcb-data, libquicktime1, libquicktime-dev, quicktime-utils Thank you so much for all your help guys!
