How can we identify the difference? Looked on my disk but I couldn't find that number anywhere.

If you put a disc into your drive and run Imgburn it IDs the disc for you on the right hand side

Just to clarify on this, I think it's actually even easier to tell.
Verbatim seem to do two versions of the DL DVDs, one's rated at 2.4x and ones rated at 8x. I believe the mkm001 are the 2.4x variety and the mkm003 are the 8x variety. However, I cannot confirm this as in the UK, I can "Only" get hold of the 8x variety. I believe some of the 2.4x ones are actually MKM003, but you can't guarantee it.

so verbatim mkm001 are the preferred discs while verbatim mkm003 are not as good. And you say that you can tell the difference in ImgBurn!! But that's AFTER you've bought them! How can you tell which is which before buying so you can get the right ones?

Yeah, this is going to be a pain in the ass. Time to get a xk3y... probably.
Where did you get that from? He said both were supported.
