Oh, by the way, let me pile on to the "Memorex CD-RW = poor quality" heap. Here is a Memorex 12x CD-RW that came with my Memorex CD-RW drive (which itself is fine quality - being a LiteOn at heart):
This disc was actually made by Infodisc. What a waste of polycarbonate...
Here's my ATIP from Memorex 4x 700mb discs:
Memorex 80 Minutes (700mb) CD-RW- HORRIBLE AVOID AT ALL COSTS
ATIP: 97m 25s 30f
Disc Manufacturer: InfoDisc Technology Co., Ltd.
Reflective layer: Phase change
Media type: CD-ReWritable
Recording Speeds: min. unknown - max. unknown
nominal Capacity: 702.83MB (79m 59s 74f / LBA: 359849)
SMART-BURN Speed Limit = 4x
Memorex would be smart to keep Taiyo Yuden making the cd-r's and move the cd-rw's to Mitsubishi Chemicals (aka Verbatim quality).
They're really making a bad name for themselves in the past year by keeping with Info Disc.
