I just tried 710 beta, after installing I noticed my pchdtv was not being utilized, and there is no documentation for it on the wiki:

Is this correct? or should it have been recognized as a cx88 card?
I'm a little on the late side, but this has now been posted by Zaerc and references the 5500 as the steps are the same.
