[vdr] Re: mplayer.sh: solution of DVD chapter selection with mp3/mplayerplugin

[Onno <onnok@web.de>]

Hi,

just to ask if you treid it, do you know that
i should be possible to switch chapters using a lirc
remote and creating a lircrc file for mplayer ?
(or even using the slave mode ?)
in the worst case mplayer would need to generate a
playlist for that dvd before playing, but since i dont
have a buyed dvd here now i cant test, but only
ask if you tried it and what your experiences where.

Regards Onno
