Video hangs on OE 2 beta

[Sinister]

I just installed openelec 2 beta. When I play en video the screen stutters and hangs/freezes. If I press the menu button it plays fine in the background :dry: Also when subtitles apear on the screen the video plays fine, when they disapear it hangs again.
I have an ati 5570 graphics card. It worked fine on 1.02.
Any ideas?

Thanks

Never mind, had to switch of XvBA shared surfaces in video settings.
