Abstraction layer VLC/MSDVD

[Spellcoder]

I'm trying to make an abstraction layer in Javascript for VLC and MS(VidWeb)DVD (activeX for playing DVD).
(meaning calls to my own functions get translated to the preferred player).

This way my webapplication can choose between MSDVD (stabile, very complete instructionset, audiostream info, access to title/root/audio/angles menu's) and VLC (platform independant, filters, not limited to one videoformat, nice forum, though very unstable in 0.8.6).

I'm looking for people who have experience with using MSVidWebDVD in either IE or Firefox or have tried to make an abstraction layer to support multiple videoplayer plugins. (I know the people from Songbird also made something like this, so I'm gonna look how they implemented it too).
