It's impossible to include every media in a review - that will cost too much and take even more time.

Maybe it would be better to replace some of the media types with sony media? What do you think?

Sony media is only available as 8x here - was it 8x you were thinking of?
Moser baer DVD media is about impossible to get here.

For 16x media - all 16x media I could possibly get here is already included in the review. So you can't request additional 16x media tests without providing me with the media first
