Got problem with Oppo BDP profile.

MKVs are playing excellent but e.g. avi files are not seen in player's browser.

If I choose other profile (right now I don't remember which one) , avi movies appear in browser (as MPEG)
but choosing them goes to the browser back.

Sometimes other profiles make all media files as MPEG but nothing works then.

IS any other way to edit/customize profile files or manual only? Some wizard or utility would be great.
