I was just wondering.. is there a way to OC the graphics chip? PoverVR SGX530? I have a video compressed with xvid at 1.6 Mbps and the playback isn't smooth even though the cpu usage is about 80 % (900/500 MHz kernel). Would overclocking vga help? I know that the extra heat would probably fry the phone, I'm just curious.

// Never mind, xvid is probably badly optimized. h264 at 2 Mbps average L3.0@baseline plays just fine even at stock cpu/dsp.
