I mainly use my GP2X to watch a LOT of anime on it. Unfotunately the GP2X will literally drain a fully-charged 2500mAH pair of Energizer batteries in about 20 minutes (one episode length) when using the 'Normal' mode on the video player. 'Save' just skips and lags like a dial-up modem so I usually never use that option. I've used pocketdivx to encode my episodes to a resolution of 320 x 240 and default settings for both the video and audio quality. To the others who use Pocketdivx, what are the settings that you used when you re-encoded your video files? I think it's just me not tinkering the settings correctly
