Sounds like the TGY03 frisbees I got in the 2 for 1 scam... err... sale on the JVC PrintPlus DVD-R (cakebox). First time DVD-R Verbatim's burned better than TY for me on any of my burners.
On the other hand, the the TGY03 Silver Inkjets (tapewrap) I bought at the same time ranged from bad to below average for the first 70+ discs and then magically burned excellently for the remander of the spindle.
Burned a few old stock Silver Lacquer TY02 DVD+R (about 2-3 years old) (cakebox) to see if it was the burners/software - Nope! Sweet burns of mid to low 10K PIE's and under 100 PIF's for many scans.
Either quality control, shipping/handling are crap or both. Maybe TY doesn't give a crap anymore.
