Anyone test these yet?

any opinions on these, in terms of scans?

MAM-A Archival Gold DVD-R

TDK Medical DVD-R

Delkin Gold DVD-R

Verbatim Medidisc DVD-R

anything MAM-A is generally not good, plus they used faked TY mid codes.

The rest should be covered in threads in this forum, according to mid. If you have Nero CD-DVD Speed, pop in a DVD blank and see what mid it gives you, such as yuden000t02, mcc003, mcc02RG20, etc.
