Unfortunately, I'm still having video/audio playback issues with choppy video and audio. I've tried uninstalling Canola with the Canola uninstall utility several times in a row, then rebooting, then installing everything again. It appears as though I have mPlayer .26 official verson from the extras repository. I don't have any devel grade repositories installed (as far as I can tell) and I have no idea how to remove python-launcher, or where it's located.
I'm using a 770 with OS2006. Just updated. Canola begins to load and then goes into an endless "updating media library". Only way to stop it is to use the taskbar tool that allows one to "kill" a program.
