Firmware Update Problem

[Saka Wannabe]

Hello,

Recently I had downloaded the latest Firmware (UPDATE_BDPS300_VER0420) for my Sony Blu-Ray Player. Along with downloading the update, I printed off the instructions and followed them closely. Instead of using a CD-R, I used a CD-Rpro, not thinking that it really made much of a difference. When I placed the CD-Rpro into my machine, it did not say "DISC DWLD" on the face of my Player, but read "DATA DISC" instead. I waited for the recommended 30 minutes that the procedure was to take and nothing happened. Does this mean I need to go out and buy a regular CD-R, instead of using CD-Rpro?
