anything smaller then 3-4 mb can be downloaded using some
settings in mYTube like maemo-mapper does with the repository
list.

It will not distributed in deb (some people will like their own
version of mplayer, or don't like to download a big deb),
but can be downloaded after launching the application and
choosing to donwload that stripped version of mplayer.

Anyway, you've done more then enough with this version, with flv playback and seek working great. Cheers to that!
