Question, is there a good reason for making this latest version of SleepAnalyser (the devel one) include a dependency on mplayer (and libxinerama1)?

I get that SleepAnalyser CAN use mplayer for certain things, but I for example don't use mplayer or the mplayer's features at all, and I don't really want an extra media player backend installed just to have SleepAnalyzer.
