we have a saying here in Germany: there are no stupid questions, 
there are only stupid answers ;-)

Right now, DistantDVD is not supported by Remote Buddy directly. The 
sole reason for this is that I never got DistantDVD to run on my 
Macs, so I had no chance to play with it.

Constructing your own behaviour should be pretty straightforward, 
though. Please have a look at the Behaviour Construction Kit demo 
video on the "Developers" section of the Remote Buddy website. It 
should give you all the info you need to create a behaviour for 
DistantDVD in minutes.

Please feel free to ask if you encounter difficulties.

Best regards, 
Felix
