Numerous video stuttering and sync issues

[dadein]

Please post some more info on your system specs:
Processor, RAM, Video Card, etc. and how you are connected to the internet.

Ok so I've updated to the newest version;

Does this mean you updated Boxee AND libvdpau1 ?? I ask because libvdpau1 has been updated to 0.4.2 and I seem to remember having similar issues before I updated.

Also, is VDPAU displayed anywhere on the screen when you press 'i' on the keyboard while the video is playing? If not try 'forcing' it by toggling "Enable hardware assisted decoding when possible" in Settings > Media > Advanced. Once it is unchecked the line below it will no longer be dim. Make sure it is set to VDPAU and then restart the video.

System is a C2D 2.66Ghz with 2Gb RAM, onboard Nvidia gpu.

My card isn't VDPAU compliant so I've never tried selecting it in Boxee, I'll run an apt-get update on the machine just to check I have all the latest versions and try running with the VDPAU method.
