Once you find a CD-R that's compatible with your system, then stick with it. I've been using these regularly for a couple of years now, and find them to be reliable with my HP laptop, old Toshiba laptop and my HP desktop.
I had a batch of Maxell and Phillips blank discs, and for whatever reasons, (incompatibility with my system?)- about 70% of them would eject in the middle of burning. So for now I'm sticking with TDK, and at 20 pence per disc, I won't cry if I accidentally make a coaster!
