I've never had any problems with Memorex discs, I've actually found that they're generally the best.
Every time I buy a large spindle of a difference disc type I end up with half the spindle being useless.
Not the case in my experience. While less than "half" of Memorex discs I run across are bad, there have certainly been a large number of cases where they simply weren't compatible with a brand of burners, or they were flaky.
I don't run across these issues with higher quality disks like TDK. This is actually why I specifically seek out TDK's also when doing customer data backups at my old job. I would not be exaggerating at all when I say that our shop would go through a 100 disc spindle a week... and you could ask those that worked with me, too, and they would agree on the topic, too.
And whenever we had a flaky burner come in for a diagnosis, we always required the owner to bring in some of their media, too. I would not be exaggerating if I told you 6 times out of 10 it was low-quality or incompatible media, not a problem with the drive.
It's great that you've had good luck with Memorex... if it ain't broke, don't fix it.
However, in CF87's case it is broke, and I'll lay you odds it's either a dirty lens or the discs themselves.
