There aren't any playback problems with these. I have verify turned on in programs I use for burning (ImgBurn, Nero), that's how I noticed problems with MKM 003 in the first place. First disc had some strange speed fluctuations in verify, and second one even failed verify. I burned them at 4x, 7203s didn't offer 2.4x. I had no problem with MKM 001, I burned about 20-30 with liteon, but from about 8 003's 4 were unreadable from second layer, 2 were readable, but scanning froze at layer break, and other 2 had about 50 quality so they were sort of OK.
Just tried burning Imation +R DL, Ritek S04 at 6x, if MKM 003's had scans like this I wouldn't complain one bit, although it made some strange vibrating noises during burning
I'm sort of glad that I'm not the only one who has problems with these discs :bigsmile:
