I have a Sony 5-disc player that we got back in December 2002 on sale, and by then it was already obsolete. I do like having that kind of disc capacity precisely because I don't have to juke around putting discs in and taking them out. In fact, the constant change-o with the video player was what prompted me to get the 5-disker to begin with. I don't program my mish-moshes per se, but I know the points on each disc that I can "mark" immediately before the beginning of each workout, so it has the same result.
Sony, I believe, now has a SIX-disc player. OH, HONEY . . .
