Thanks for this link, I already evaluated this frontend when considering what to use for MPlayer GUI on Nokia 770 (along with others from http://www.mplayerhq.hu/design7/projects.html). It worked somewhat, but was not very usable and still needed a lot of tweaks anyway, in addition it has python as a dependency and that may be not very desirable. So current GUI was written from scratch and is specifically tuned for Nokia 770 (it matches my vision of best usability - requires minimum efforts to find and watch any video stored on mmc card and is also usable without stylus).

Surely, alternative GUI frontends (and improvements for the current one) are very much welcome. Don't forget about mplayer garage trackers, they can be used to submit bugreports, feature requests and patches, so that issue reports do not get lost in a long forum thread
