I've just installed the latest version of Itunes on a clean Vista Ultimate 64bit install. Everything seems to be working fine for audio but video playback is very choppy.
I've tried enabling/disabling the DirectX acceleration for quicktime. My system is an A64 X2 4200 with 2GB RAM and an x850xt pe so its not a lack of power. Video plays fine in all other programs (WMP, Flash etc). I'm using the ATI 64bit drivers for RTM, not the ones that came with Vista.
It's not even high-def content or anything, just some video podcasts. Any ideas people?
