I just recently purchased from Taiyo DVD-R media from Rima.com. I went to Rima because of the good reports that they sell genuine TY media. I'm a quality oriented person and always try to buy the best media.
I have three DVD burners at home. A Pioneer DVR-106, NEC ND-3520A and a Lite-On LDW-451S. I usually use the Pioneer and NEC, with the LiteOn being mainly used for Kprobe scans.
My last batch of 4X TY media was excellent. I received the new batch of 8X TYG02 media yesterday. I took 3 discs and burned a bunch of files to test the media on each of my 3 burners at either 4X or 8X, depending on the burner. What I found after a Kprobe scan makes me sick. I don't know if I should just throw them all away, or return them to Rima (if I can) and just buy a new batch. All the media has the genuine "GG" code on the rim, so it appears to be real TY media. Did their QC go down hill?
All these were scanned with KProbe at a 4x speed. 8x was just as bad, if not worse.
Here is a scan from a LiteOn burned disc, burned at 4X.
Here is my Pioneer, burned at 4X.
Here's the NEC, burned at 8x
For comparison sake, here is a typical good scan from one of my older 4X Taiyo media burned on my Pioneer.
Big difference from the above pics!
Can anyone tell me why the 8X Taiyo media is so much worse than the 4X Taiyo media? I used three different burners, but the only constant was my LiteOn doing the scan with KProbe. However, it does show that it can scan other media correctly, so it can't be a bad reader.
