Tiger bits: This slow, slow DVD death...

So I decided to make some DVD backups of some files that are just sitting there unused on my hard drive, in order to free up some space on my Powerbook. I stuck a DVD in and chose to have it be opened by the Finder. I drag the first 1.8GB folder over to the DVD and wait for it to copy with no problem whatsoever. I then drag another 1.3GB folder over to the DVD and it begins copying the files, but about a third of the way through the progress bar stops progressing and I am presented with the spinning beach ball of death.

I am a patient man, so I wait, chatting and surfing the web, and doing things that do not require access to the Finder. After about 7 minutes, the DVD window jumps back to the front, the spinning beach ball of death is gone, and all the files have successfully copied.

I still have a good amount of free space on the DVD, so I start copying over one final folder that is only 187MBs in size. It gets about a third of the way through and suddenly I am presented with a spinning beach ball of death again and Finder freeze. After another good 8 minutes it finishes. Repeatable bug? Any one else experiencing this? 10.4.1 on a Powerbook G4 1.33 with 1.25GBs of RAM.

UPDATE: I'm an idiot. Burn folders rule!
