what is the main difference between the pioneer DVR-A03 and DVR-A04?
Also what type of disks can i burn, cd-r, cd-rw, dvd-r and dvd-rw or dvd+rw?
Which one would you recommend and how much should they be?
My friend can hook me up with the dvr-a03 for $400 and dvr-ao4 for $500, which is a smarter purchase?
Thanks in advance,
David....

I would get the A03. I have one, and it burns every single disk that you listed. Has no problems with OS X, whatsoever....

I dont think either will do +rw or -rw. But I think the main diference is speed. the higher number being faster. I am pretty sure about this but dont hold me to it.

thats the only difference I know of

The A04 is faster, go to the Pioneer site for more info.
