']The 16X DVD-Rs around here in that spindle are PRODISCF02. :a
Yep, that's entirely plausible. Prodisc is now using TY-lookalike packaging for some spindles, although you can tell the difference... Prodisc spindles have a completely smooth cylindrical bottom, without the little 'ribs'.
The sure way to tell Prodisc media is to read the code off the silver area about 1/2 inch from the center. Prodisc DVDs will have PRNN-NNNN-NNNN (+R) or PFNN-NNNN-NNNN (-R), where Ns are digitis.
