Hi Guys, Thought I'd post on here since I've had no luck on the VLC forums as I'll explain. I've got a 2006 MacBook, 1.83 Ghz CD, 2 GB RAM and a 5400rpm 320 GB drive. Still chugging along nicely but not as it used to! My problem stems from VLC or rather, VLC when using 10.6. When I first upgraded, I had to stop using VLC and use Quicktime, which even with Perian isn't nearly as good. Essentially, whenever I moved the video onto the 1920x1080 screen in full screen it starts stuttering to the point where it's unwatchable. This occurs with standard xvids and also x264 encoded 576p, 720p. On 10.5 it's perfectly fine but on 10.6 it just drops loads of frames. When I asked on the VLC forums I just got told the Intel GMA950 just couldn't hack it but yet it hacks it perfectly fine on 10.5. It's just annoying now that there's proper divergence between the two OS's with the App Store and certain apps going 10.6 only, as has iLife. Any ideas would be greatly appreciated!
