I have this problem with ubuntu-11.04-desktop-amd64.iso and ubuntu-11.04-desktop-i386.iso downloaded from both the main site and torrent.
MD5 checksums match. Content burned to CD-R using Brasero through Ubuntu 10.4-desktop-amd64 on an HP Pavilion DV4 (DV4-1200US) which is what I was trying to load the live disc on.
With both Operating Systems the live OS could not be loaded and the CDROM won't read afterword-- I have to eject the CD and reinsert it (or completely turn off the laptop) if I want to try booting off the CD again.
