AFAIK They use completely different video access. Mplayer and most of the games you talk about render through XV (so, no GTK, no universal RGB pixel drawing, no nothing). FBreader, on the other hand, uses regular X with GTK, and in *that* mode, video operations like scrolling are painfully slow (lcuk can tell a story or two on this).

Could you elaborate on why the autoscroll feature would require a complete rewrite of fbreader? I would like to hear a technical explanation, if at all possible. Thanks.
So you'd have to do a serious rewrite to adapt everything to XV style operations, redo the whole interface, adapt font rendering to YUV, etc, at which point you're closer to a rewrite than a patch and it would be very maemo/linux specific.

I'd ask for any better informed person to say if I'm wrong here, as quite some time has passed since I've looked at fbreader innards.
