I have yet to see any JVC TY in any retail stores. BTW i have not seen any branded TY in retail stores in years in the USA. I have yet to test any of the new DVD-R 16x JVC TY...some who has please chime in.
As for JVC, IIRC i last saw some at HR Gregg's, but it was not TY or even made in Japan.
I will not be buying any JVC TY DVD blanks unless i run out of 300-spindle count of Verbatim MCC 004 and MCC 03RG20.
I will probably buy and test some JVC TY CD-Rs soon...
