Here's my settings on TCPMP:
1)pixel aspect ratio-->
auto
2)
Intel Xscale video driver selected
3) Hot key assigned for exit (prevents Q from freezing white screen if exiting any other way)
4) Buffer
4992
5) Preload at underrun --
80%
6) preload for audio 128 (prevents A/V out of sync problems)
I also have a fast
150x ATP MiniSD from
www.usamemory.net that kicks some major butt. Also install TCPMP to your memory card. It also helps to kill all your tasks prior to watching video and install the update. TCPMP loads movies alot faster and has higher benchmarks with the new update.
