As long as those filters are installe don you system, BSPlayer can use them. And I am refering here to:
-Gabest MPEG2 filter
or
- Intervideo (Corel) MPEG2 decoder
- dvd source
or
- Cyberlink MPEG2 video decoder
- Cyberlink dvd source
If you go to BSPlayer preferences -> filter management, you can select here filter priority (which filter to be used)
As for gabest filters...
