install lenny on Dell

[Tom Poe <tompoe@meltel.net>]

I bring up stuff on my computer, and it has an icon with CD-RW/DVD-ROM 
drive.  I downloaded a lenny i386 iso image, and used brasero to burn it 
to a Memorex DVD+RW disc.  I shut down computer, started computer, got a 
blinking cursor for a few seconds, and then moved to ubuntu (installed 
operating system).  Does this sound like I have to go buy some other 
discs, because my drive is too old, and can't read the DVD?
