while suffering from the OVP crisis , I suggest using kmplayer + mplayer...
It allows you to carry on playing videos in the background too with one caveat; the video won't be seen when its minimized...so you get a blank screen but the audio of the said video keeps playing on...I got a quick reply from the Project admin, Koss, stating that this is an unfixable bug...


Edit: If you require there is a slightly updated mplayer available too in the interwebs but it isn't really much of an improvement...in kmplayer I just select gstreamer+mplayer as my backend as choosing mplayer solely gives a out-of-sync audio/video...
