The Logic Off Topic list

I used to use toast titanium on my G3. It was so easy to choose some 
files then burn. Audio files were easier to manage than stupid iTunes 
which forces you to import then create a playlist etc.
I have some folders I want to burn to DVDR on OSX10.3.9 and I don't 
know how to do it. I looked at disk utility as a possible option but I 
don't know how to use it and the help for 'disk utility' doesn't have 
any info on using disk  images.
Do I need to buy some software? I don't have a heap of cash so a frugal 
solution would be welcomed. Why doesn't OSX have a simple burning 
application like 'toast'?
Thanks for any help,
Roman.
