I am looking to change my media brand to Prodisc as I used Princo with never a problem and they are cheap. But now I have moved so I am not able to get the Princo's from my main supplier and have to purchase online now. My question is I have a PS2 and Xbox but wanted to know definitively will they work ("-R" type) with both. My PS2 reads Princo "-R" burned at 4x and my Xbox reads them burned at 8x. I am quite positive they will work but would like to know of some people that can confirm this. Thank You for any help.
