I have Interactual 2.7.
I have several DVD's with IA on them.
I can play a DVD, I get video but no sound. Once in a while I may hear a "blip" of a sound but that's it.
Also, the DVD says it has "enhanced" feature for which you need to be on the web, but when I try that, I get a "file missing" error.
I am able to view and hear movies from the web with no problem.
I have the latest video card driver (5/09)
I have the latest sound card driver (4/09)
I have the latest DirectX file (9.x)
I have Windows XP SP3
Intel Duo Core 2.33G
2 Gig RAM
I can play the DVD just fine on CyberLink Power DVD! However, I don't get the enhanced version stated on the DVD.
