jmscott42 seemes to be the resident Verbatim expert here on AVS so perhaps he could clarify a few things.
The 2 Verbatim 50 count spindles I bought about 10 months ago at Best Buy ( had them match Office Max's sale of $7.99? each) had the MAP6 code and I had no problem with them. Unfortunately it seems as tho my Toshiba/Samsung burner in my HP computer will not allow me to use DVDINFOPRO to do quality scans of discs.. However, I checked the disc on DVDIDENTIFIER and it was made by Mitsubishi (MCC 03RG20).. But I recall Verbatim also had CMC make some discs for them and let them use the MCC media code. If this is correct how can one tell if they were really made by Mitsubishi or CMC?
About a month ago a couple people in Italy and German sent me some Verbatim discs. A -R and a +R and I could tell by the distinctive ring on the disc that they were made by Taiyo Yuden.. I confirmed this by checking them on DVDIDENTIFIER..Looks like people in Europe are luckier than us here in the States when it comes to Verbatim, tho they probably don't get them as cheap as us, at least when they're on sale.
I also recently got a Panasonic disc from someone in the UK and it too was made by TY..
