Hi,
this may not be related, but I once had an ACER Aspire 1501 lmi Laptop that crashed during installation of linux at roughly the same stage. I also tried to burn the cd multiple times but wasn't successful.
Then I realized, that the processor was always running in full speed because processor heat management was not yet installed. I could install only by letting it cool off completely and trying all to prevent it from overheating during the installation process, but then it worked well.
Not a funny experience, but then in hindsight, it was...
