I recently purchased a rebadged stack of Value-Line discs. The packaging has a "Value DVD-R" label attached, but they added a JVC sticker that says "For Professional Use". Needless to say, it was sold as an official JVC product.
Quality appears to be the same as typical Value-Line - dye blemishes on some discs, higher error counts, etc. I haven't burned enough discs to gauge failure rate, but I'll assume that it should be the same as my previous Value-Lines (for every stack I've tried, at least 15% of the discs struggle through a TRT).
As with any Taiyo Yuden product, discs that pass a TRT with a smooth curve play back fine on all my standalone players. Nevertheless, it's a bit concerning that these can be passed off as "professional quality".
