Questions and Answers
Q: Will there be a finger-based frontend for easy and quick using?
Q: Is there anything i can use just to see video playing on the neo?
A: Yes, there is a version of mplayer floating around somewhere (mplayer-arm920t) which runs on the neo. URL unknown, ask in the IRC channel for a copy. It seems to play MPEG files around 320x240 at an ok framerate. (It needs a lot of FLASH space though...)
ipkg install mplayer # working from "official" repository now mplayer -fs -ao sdl -vo sdl -framedrop <filename> # get the best speed using SDL
