Hi guys, we are in beta, so being honest there's a lot more problems than those but we are working hard on several fronts to fix several issues each release. So: videos, I will check to see if that's the case, but yes we do ask mplayer a window, don't know if that looses quality in the process, but for sure canola uses some cpu, then mplayer using full cpu can be fighting for it causing framing skips.
