The way I detect if a DVD is inserted it by using the code from the Audio CD side of things. Theres a guy at Microsoft who released a class to let you burn CD's (

So if there are any weird detections....afraid its nothing to do with my code
Ive thought about whether it would be better to use a common program for both CD's and DVD's (I use cdrecord.exe for DVDs) but the codes there and it works (for most ppl!)
