I had similar problems. So I installed 3.1 with an external USB CD reader. That worked fine.
But when I tried with 3.2 it didn't work at all so I had to use my very slow internal CD reader. But that worked when I upgraded since it took less time than a full install. That is, not a full 30 minutes.
So maybe you should try the same: use an USB CD reader to install 3.1 and then upgrade to 3.2 with the internal.
