Sorry if this is a dumb question, but this is my first post and I'm a little nervous. My question is this... I see a lot of posts regarding problems with back-ups being related to the quality of the media. I always see the "ritek" name thrown around on this site, but I have never seen this brand sold at any store I have been in. Are these disks manufactured by ritek and sold under another brand name, or do I just not live somewhere that carries them? Also, I have backed up close to 50 DVDs using TDK DVD-R 4X that I can buy on sale for 19.99 for 25 disks. They record a little slow, but they play on my Panasonic DVD players and my computer with no problems. My concern, and the reason for this post is, will these "inferior" disks wear out faster than the recommended "ritek" disks? Any help would be greatly appreciated.
