I heard that to distinguish a real mitsubishi (verbatim) dvd, you have to check its hubcode.
For either DVD+r or -r, it’ll be something like ZD…-DVR-…
What about cd-r?
PS: Last time I bought a spindle of Verbatim dvd-r with media id MCC 03RG20 from my country’s supermarket. On the package, it said made in India. The price’s not cheap but the packing is very lousy and the disc seems lousy too (there are somewhat watermarks on the clear plastic part in the centre). “ZD…-DVR-…” can’t be found on the hub, only “722M” and “DVD-R” are seen so it’s fake. My money~~~ (sob)
