There was at least one recent series of posts on this topic. Apparently, some of the system discs coming with new Macs are much larger than before. Unfortunately, many of them seem to be above the capacity of standard DVDs so that the ability to burn a copy for backup has been lost.
I don't believe anyone came up with a solution but I'll post back with a link to the discussion if I can find it.
P.S. Here's a link to one such discussion:

After finding that the prices at local stores were rather high, I ordered a 3 pack of Verbatim DL DVD+R online at a reasonable price with free shipping.
I just successfully burned the .cdr image and my iMac recognized it as a startup disk in System Prefs. Have not had a chance to try it, but can't see a reason why it wouldn't since the computer recognizes it.
I just ran across this technique in the Mac forums at Ars Technica. It uses terminal and allows you to ultimately burn the Mac OS X installer on a regular DVD. I have not tried it myself.
"Step 1: Convert the DMG to an ISO (by using the CDR Master option in disk utility).
Step 2: in terminal type:
hdiutil -mount path/to/file.cdr -readwrite
Step 3: Drag the developer folder out of the read/write mounted disk and into the trash; empty the trash.
Step 4: Unmount the image and burn it to a standard DVD-R"
I wanted to include this for completeness sake. Perhaps it will come in useful.
