Maybe there's a conflict with another mediasconf.xml from another directory?

I just had a similar problem, that it wasn't loading all my filters, then I removed the mediasconf.xml and filtersconf.xml from "XBMC/system/players/dsplayer/" and only keep the ones in "XBMC/portable_data/userdata/dsplayer/" (in my case, I run the portable profile "XBMC.exe -p" ).
I don't know if was that, or I did something else, but now everything is OK.

Thanks, I searched my entire drive looking for other copies of these xml files and they seem to be the only ones...
Also, creating a filter graph directly using these filters still works fine using graphstudionext so I am sure that the filters are registered and working correctly...
