Playing compatible video files in MediaPlay without renaming

[geo650]

Hello!

MediaPlay can play many video file formats (containers) like MPG, AVI, VOB etc.
But it doesn't know some file extensions that it could play well, too.

I am trying to add MTS extension support for MediaPlay.
(FYI: MTS files are recorded by some still/video cameras and can contain playable H.264 video stream; to play this file in MediaPlay, you can rename it using TS, MPG or other known filename extension)

First, I was trying to edit exeDSP image to replace "svi" extension (unused by me) to "mts".
I have found 3 occurences of "svi", but MediaPlay didn't see MTS video files after changing "svi" to "mts".
Then I tried to find a list of allowed video files' extensions (svi, vob, mpg,...) in other places - but I couldn't find anything more.

Now, I am wondering if MediaPlay engine is hidden somewhere outside exeDSP binary
or is it encoded so deeply that I cannot change video files searching mask?

Alternate question: is there any other method to force MediaPlay to play MTS files without renaming them?
