Re: Youtube Video Playback on Neo Freerunner? (Re: Video Playback virtually impossible on Neo Freerunner?)
Just thinking out loud here, as I probably have no clue what I'm speaking about, but what about something like XDamage, that only updates the areas of the screen that have changed?

Thats my project, btw. My biggest question is how decent the hardware scaling is. Could it scale 160x128 to fullscreen?
