Hi, I just installed a HP DVD 1040i DVD drive and am unable to play DVDs using the Nero Show Time Program that came packaged with the drive or any other player as well. When I press play I'm prompted with "Internal Error. Cannot build graph. The application may be installed incorrectly." If I go into Nero Essentials SE I can play the DVD but there isn't any sound. I've tried playing audio CDs and other burnt media and it works fine. I have tried: Using the Clean Tool and reinstalling the software. Downloading codecs from DivX and K-Lite. Playing the DVD in other players (Windows Media and VLC Media Player) using the start > run > regsvr32 "C:\Program Files\Common Files\Ahead\DSFilter\NeAudio.ax" fix that I've seen recommended. I wasn't sure if this belongs in the Drive or Nero forum so I hit up both as it seems to be a drive problem since DVDs won't play in players other then Nero. None of these have helped. Is there anything else I can do or is there something I'm doing wrong?
