Hey E-Male, Well,even though I got it working before, I had to reinstall windows and now whatever I do now that I did before, etc...I can't get the Dolby Headphone option to come back in graphedit.. Can you tell me what version of claud.ax you have and what your registry settings are? Mine is the 3.5.0.1004 - 208kb 10/4/2001 NEVERMIND!! Just downloaded the Japanese PowerDVD5Deluxe Trial and it's new filter works perfectly and has many more options - i.e. you can use trusurround xt headphone (even though it's not as good), their new stereo->multichannel and more in GraphEdit. Only catch is you have to use Cyberlinks own WAV Dest filter. The english version , was just released today on sharereactor/software - few sources as of yet.
