Unfortunately I can't edit it, but please consider my above table changed to:
TDK +R 8x (TDK-002-00): Good
Verbatim +R 4x (MCC-002-00): Good
Memorex +R 8x (CMC MAG E01): Good
Sony +R 8x (SONY-D11-00): Average/Crap
Samsung Pleomax +R 4x (OPTODISC-OR4-00): Average/Crap
MMore -R 8x (FUJIFILM03): Really Crap, or maybe I just got a bad batch. Reported to work better in B7P9 though.
Emtec +R 4x (VDSPMSAB-001-01): Forget about it
As I was previously using a defective drive, apparently. The new one I replaced it with seems much more on the level. I'm also testing the media properly with Nero CD Speed now.
And why doesn't DVDR media have the media id code they're using printed out in the box ? How are people supposed to know what they're buying ?????? Sheesh.
Now that I've got the basics, it's my turn to cross my fingers like everyone else and pray for all my backups not being unreadable in two years from now. What a mad world.
