BSPLayer with powerdvd's ac3 decoder?

PowerDVD 4.0 (deluxe at least) has dobly headphone decoding.

If I pick to use cyberlink's ac3 decoder in bsplayers setup and then play a movie there is no sound. Also if i do properties there isn't any choices even.. just stereo.

Is there no way go get dolby headphone using powerdvd's ac3 decoder in bsplayer?

Also wierd thing i just noitced... there was no sound comming from bs player, i opened powerdvd and all of a sudden sound started comming from bsplayer... wtf?!

Is there any ac3 decoder that works in bsplayer better than intervideo's?
