Open Program when DVD volume is mounted

Hello everyone,
I am pretty new to Hazel and was wondering of how to accomplish the following task:
I want Hazel to open a specific programme when a DVD or a BluRay is mounted via my disc-drive.
So I though of doing this by: If the mounted folder contains a VIDEO_TS folder, open programme XX, if the mounted folder contains a a BDMV file, open programme YY. Would this work or is there maybe even an easier way of doind this? And I was wondering of how to access the volume folder with Hazel.
any thanks for your help.
