I'm using Ubuntu 10.04 and have it hooked up to my HDTV. My GPU is an 8600 GT and I am using the current nvidia driver. Mother board is GIGABYTE GA-MA78GM-S2H, CPU is AMD 4850e, using 2x1G ram 800MHz.
Everything I have installed on it comes straight through Synaptic. Smplayer seems to work fine with the VDPAU selected (cpu usage is nice and low during HD playback), but there is a slight problem that really annoys.
Every 2-3 seconds the picture seems to have the hiccups, its as though it gets stuck on one frame for a split second and then jumps to the next.
I'm looking for some suggestions to try and fix this.
