DVD media check program

[dckim64]

Hello all...
Just trying my luck with my first DVD burn. Received some Ritek2x media from Allmedia and there was no labels with this shipment. Could someone point out the best (or any) programs to check if the DVD that I received is actually Ritek? I heard about DVD Decrypter but I see nowhere in the program to check for media type. Are there different kind of Ritek 2x (ie, different manufacturer of Ritek 2x)? Can one get a 2x Ritek that is lower quality than another batch of 2x Ritek from another company? Thanks...and any tips before I try my first burn would be appreciated.

cdspeed.exe (free from Nero) will tell the manufacturer, speed, etc.

Does CDspeed work with DVD media? I actually tried to use CDspeed but I could not find the command to check it. If you could, please let me know how to use the program to check DVD for the manufacturer's info. Thanks...
