Query: My worst experience with any media, ever

I bought these for my Mini-DVD Sony camcorder. Most of the disks give me read-errors when I try to view the recorded movie. I've been throwing the defective ones to the trash, now I have about 5 left. I'll buy a different brand and throw them all (verbatim worked like a charm before).I can still save the video (as usual transferring the DVD's to my hard-drive), but there are lots of hiccups due to the very many defective sectors. I have never, ever had such a miserable experience with any media.
