I have had absolutely no installation problems, nor am i aware of this being an issue for anyone else and their machine(s). When it comes time to change CDs during the installation, i just put the next disc in the tray, click the button on the screen to continue, the tray closes, the drive spins up, and it continues just fine. Can you mount all of the installation discs normally on an existing machine? At the beginning of the installation, you are given the opportunity to run an integrity check on the disks. Do this for each disk. If it's a media or data integrity problem, you'll know right away. Also run the md5sum check on the iso images: md5sum -c ./MD5SUM . This is done in the directory where the MD5SUM and iso image files are located. If none of this helps, i would try swapping out the cd-rom drive; some sort of timing or spin-up problem with that particular drive or model of drive?
