If you’ve ever stood on the blank media aisle at Best Buy, wondering whether those expensive name brand DVD-Rs or are really better than the cheap ass ghetto nondescript blanks, then you’re probably not aware that most of blanks are actually made by a small group of manufacturers and rebranded by the big boys. Yea that was a long sentence.
Anyway, digitalFAQ has compiled an extensive, possibly exhaustive list, of which blanks are made by which manufacturer. Since blank DVDs still cost an absurd amount at the brick and mortars, I recommend checking the FAQ out. It could feasibly save you $20, which you know you can use for something more exciting (like these).
