As for the CD issues; One of the big ones so far as Vue is concerned is one of their anti-piracy systems. There is a final pass that stabilizes Vue upon installation, and that has to occur from the CD. There have been several rips of Vue 4 and VuePro dropped onto Usenet, and none of them have been stable. If your CD drive has trouble reading that seperate track to fix things, then you have the instability to contend with. The buffer issue has to do with the fact that current hardware can demand data at a far greater rate than the CD drive electronics can provide it (buffer underrun), or the media is rotating so fast that -it- is providing data to the buffer faster than it is being emptied...and can overwrite itself (buffer overrun). Then there's the firmware in the drive itself, that may conflict with your system (get the feeling I've had this trouble before... ;) ).
