This particular thread http://ubuntuforums.org/showthread.php?t=476677 I wanted to respond to was a read only archive; I just wanted to add to it. I kept getting the red screen on my install as well. I was using an old (but new to me) machine and I figured the cd drive was just bad. So I replaced it with a new Sony DRU-830A DVD/CD drive. The install was peaches and cream after that. So the select and install software 6% issue could be related to a bad drive? I'm not sure, I just felt obliged to post my findings. Here is the original link to the read only thread I mentioned above.
