I think your biggest bottleneck here would be detecting what operating system the user has on their pc.

However, if you are assume they are using windows you can definitely detect the cd-rom drives.

For example the following snippet:

works when using bloodshed (tried and tested)

http://www.bloodshed.net/

I'm not sure if that's what you mean?

Thank you iamthewee,

That was great information. If I not mistaken in that example Media Control Interface (MCI) is used to control the CD-ROM. I was wondering if there is a similar way to deal with DVD driver?

Is there a way to create a sniffer which can keep an eye on MCI and keeps track of the the information/command (Play - Pause - FF ......) and simply display it. When I talk about sniffer, I mean sniffing to see if these commmand are send to the MCI from other software applications.

Thank you very much for your help.
