I'm confusseeed how do you tell?

how do you tell the difference between an ritek r03, r04, or r05 media?? or sony, yuden, verbatim for all that matter? can it be found somewhere on the disc? or what? please help, thanks

This doesn’t belong in the Liteon Forum.

You can’t tell by the looking at the packaging or discs, you need to insert a disc in your drive and use a program such as Nero CD-DVD Speed or DVD Identifier, they will read the media code off of the disc for you.
