I have not had time to try and reproduce it, but I have burned cds with this media at 32x before with no problems. In fact I've done this many times, but this is the first time I've had the problem with the cd getting stuck in the drive. Also I have not changed the OS since. I dont really have access to other media since I bought 100 of these, but they've worked before so I have no reason to suspect the media. I'll try to reproduce it tonight.
