Here are a couple suggestions:
1. Utilize VirtualBox. Assuming you've a computer with a virtualization
instruction enabled, and the RAM, then all you need do is point VBox to
an ISO and it will represent it in the "CD Drive" to a virtual computer.
While not exactly a response to your question, because I believe the
gist is that you want to boot with bare metal, I find this *much* faster
than burning lots of CDs, keeping track of them, and then booting off of
them. (I didn't realize just how bad the latency was with optical
drives until I used Qemu virtualization some 5 years ago.)
They've made it extremely easy to install for any distro, and after
about 15-30 minutes of futzing, you should be a pro with the GUI. It's
that simple. http://virtualbox.org/ -> "Downloads" (link on left).
2. Utilize CDRWs. Every now and then I *do* need to test in the
non-normalized atmosphere of bare-metal. When I do, I have 2 CDRWs that
I've been using for the past 4 years. They do go bad after some obscene
amount of writes, but I'm still waiting, and I use them fairly heavily
every couple of months or so.
3. If you have a spare computer, consider setting up a PXE boot setup.
Assuming you have the prerequisites in order (basically a box less than
5 years old), you can use a second computer to serve out an operating
system over the LAN. This solution is a little more "techy" and will
require some command line action, but I don't think it's that difficult.
Most of today's distros are almost-PXE ready. To date, I've booted
and installed Ubuntu, Fedora, CentOS, Mint, Debian, and OpenSUSE via a
PXE route, so I know it's possible.
Before you ditch suggestion 1 for suggestion 2, I do recommend you at
least try it. VirtualBox has come in handy for *so* many things that I
didn't even think about until I had it as an option. VirtualBox is a
