<< yessir they do, but as you said theyre 185mb and expensive as sh!t. I know sony makes them for their mavica disc cams, and they burn just fine in a regular burner too. I believe they are 4x max write tho..the sony ones at least... >>
Haha. I have a Mavica CD-R on my desk right now and I totally forgot about their CD-RW discs.
I just found a 5-pack of the RWs at Staples for $9.98.
