Summary: Works perfectly at 4X in Sony DRU-510a
Review: Makes beautiful copies. These discs are made by CMC magnetics. (CMC MAG. AF1) One of my favorite media choices. Never had a failed burn.

Summary: Does NOT work with Sony DRU-510A
Review: I've gone through three packs of these lousy discs trying to get them to work with a Sony DRU-510A burner and gotten coaster after coaster after coaster after coaster. VERY FRUSTRATING!!!
Using Windows 2000 SP4, latest drive firmware update 1.0D, roxio ECDCDv6 with all the latest patches, etc., etc., etc.Although a few discs actually did manage to get recorded, trying to add a new session to those discs destroyed most of those few survivors. Memorex, Sony, and roxio need to get together and resolve this fiasco. I've wasted DAYS and DAYS on this nonsense!!!

Summary: Trustable Brand + Proven Format
Review: I have no idea where the reviewer who wrote "I heard that +R discs were more compatible with stand-alone players" heard that but it is completely wrong. Most anyone who is into this stuff knows that -R is definitely more compatible. This has been tested and proven countless times on sites such as afterdawn.com, digital-digest.com, tomshardware.com, cdrinfo.com, etc... the list could go on a long ways. Bottom line, -R is what is more compatible with stand-alone players. That's a fact and I hope that sets the record straight.

Summary: Terrible Quality
Review: I just purchased a Panasonic DMR-E60S and these DVD-R. Over half of these could not be written by the DVD recorder. I thought it might be the unit. I purchased TDK DVD-R disc and haven't had a failure yet. I would avoid the Memorex discs.

Summary: Excellent DVD-R disks for the best price at Amazon only
Review: I got this pack last month and by now I have written 15 dvd disks using Sony DRX 510UL. All the disks worked flawless in my Toshiba sd2900 dvd player. My advise, take this opportunity Amazon has given and buy these. Its worth the money.

Summary: Great Quality, Great Price
Review: In my Pioneer DVR-106A these work flawlessly. I was able to backup data to them at 4x and I was able to create home movie DVDs that work in most DVD players I've tried them on. I also like the format of the labels on them, which make it easy for me to label the disks neatly.

Summary: Memorex 4x DVD-R Rocks!
Review: I used this with Liteon LDW-411S DVD writer with latest firmware (OF). It worked flawlessly at 4x as promised. The movie palyed well on the Apex AD-500W player. Highly recomended

Summary: Works great for me...
Review: We ordered three spindles at this great price and have gone through one without any problems. We burn with an internal TDK indiDVD at 4x. We use the Roxio software that came with the DVD burner. It works great... the DVDs work in our PS2 and our computer with DVD-rom.
