Susan,
A CD can hold 700 Megs. RW CD's are basically useless.
Now that we have double-layer DVD's, you should invest in that type of burner - though not in Double (dual) layer DVD's, as they are still quite expensive. Buy the burner, as it still does DVD 5. Soon, though, you'll be all good with the golden god.
Then again, BlueRay may be the way...
Did that help? Hehehe. Nope.
That is technology. Never was, never is.
