Well, I'm using 6.2-RELEASE/amd64, and I get those same
"Input/ouput error" messages.  However, the discs I have
burned all worked fine, so I've assumed it was just
something the program tries to test for or request info
on, but can continue without.

Have you checked whether the burned discs actually work?
