ok more info -
powerdvd7.3 ultra was no good when put in clsid or clsid2
i have now upgraded to version 8 ultra (couldn't resist)
when both clsid and clsid2 are set as powerdvd and i use the beta dll file all i get is digital audio service for bbchd
when i use the rtm dll file and have microsoft dvd/dtv codec for clsid and set clsid2 as powerdvd i get bbchd with a stuttering picture, but i get digital audio service for every other channel - so h.264 is possible with the final msdtvvdec.dll file !
when both clsid and clsid2 are set to powerdvd i get "files needed to display video are not installed.........." when viewing sd and digital audio service for bbchd!
if i use the cyberlink audio codec for both clsid and clsid2 i get bbchd picture but no sound and all sd channels with sound but no video.
i'm gonna spend a few hours doing all possible combinations of ms/ac3filter/powerdvd audio codecs as well as all video codecs to see if i find a magic combo.
