I have an issue with YouTube videos running slowly, maybe running at about half to 2/3 speed (audio and video). I'm using the latest VirtualBox (3.2.2) and latest 2.6.32-15.bfs kernel with PCLinuxOS 2010.1 KDE. I've run the Install Guest Additions after both downloads and I still get slow videos. The last version of VBox where videos from YouTube played correctly was 3.1.8. I don't want to have to downgrade.
Did I miss something in doing upgrades?
I forgot to mention the host is an iMac, 4GB Ram, OS X 10.6.3 (32-bit mode). My VBox settings are 1.5 GB RAM, 2 CPUs, VT-x and nested paging enabled, 3D acceleration enabled.
