I dont get the force-close issue much at all. But its 'experimental-ware' When I 1st installed it it wasn't optimized for DROID. But about 3 updates letter it works better. I get full screen when playing music. Im sure it needs more tweeking but I do play videos and music on it once in awhile. Id say its 65% of the way there. Uninstall/reinstall maybe?..
I've only used it for playing movies, but I have yet to have a problem. My only complaint is the way you skip ahead in a movie- I would prefer it use the slider bar like the default app so you can jump ahead an hour or so much more easily. The trade off though is that the default app skips too far forward if you only wanted a minute or so.
