You can use the SVP in conjunction with XBMC if you install the version with DSPlayer.
The latest version with the additions can be downloaded here http://depositfiles.com/files/1catka99o
This distribution is already configured to work with LAV and ffdshow.
Although I would advise to use my configs for XBMC.

Configs are made with calculations that AVsplitter installed as a system and just settle into a folder LAVsplitter DSPlayer.
Substituting the resolution to the "extra" you can adjust the video resolution which will be applied smoothly.
If something is unclear, ask. I have now works fine.
