DVD - "No DVD in the specified drive"

[GIJoehosaphat]

I get this message: "No DVD in the specified drive" and the DVD drive ejects, everytime I try to watch a DVD via GB-PVR.

In GB-PVR config the drive is set to D:, and the Navigator and decoders are set to use the PowerDVD software.
In My Computer the drive shows up as D:
If I try to play the DVD outside GB-PVR it plays fine (I am use PowerDVD). Inside GB-PVr I just get the above mentioned Error message and the DVD drive ejects.

Is there some stupid setting I have wrong that is causing this?

Help!

ZIp and attach the logs and I'll take a look.

Also check to make sure you don't have the "ISO playback" drive configured as the D instead of the DVD drive. I think they are on the same screen and might cause some confusion. Its worth a shot.
