The story, at least as I heard it, was that balanced cdroms were just fine at 52x, and could probably be pushed even further. The problem comes in when the media is unbalanced, and several layers of silkscreen ink on a commercial CD is enough to get things out of whack. I'd also suspect that any motion against the gyroscopic force of the disc could cause a similar problem. I don't get cable and I don't watch any broadcast TV aside from PBS and the occasional Simpson's episode, but I did catch an episode of Mythbusters while testing a home theater setup for a friend. Neat stuff. Is anyone aware of any websites with summaries of their experiemnts? -p. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
