When you say those CD works, you mean the machine boots from them, and
with the others skips them and go directly to hdd, right?

Can it be random and your cd drive have a problem? Hardware, I mean.

I guess your tried the 10.4 several times, so it could be that only if
it is a double problem. Bad CD and hardware.

Of course if you recorded the CD on that CD driver it could be the
same. You didn't said where you had recorded you iso and I don't know
if you try the other CDs one or many times.

I always suspect hardware first when it is a CD problem.
I recommend you try replacing the cd drive with the one in your
desktop Windows machine, if possible. You didn't say if this one is a
laptop or desktop.

You have a CD that boots there and don't boot here. What are the
differences is what I would ask, right?
Regarding hardware and bios.
btw, update the bios? What is your machine, a dell? :)

Just thought hardware was worse mentioning, even if it is a weird
problem description
