Having trouble burning BDP-S1 1.60 Firmware update with Nero...help!! - Solutions

[blackpixels]

So far I've been able to successfully download the firmware file all 51.5 MB (54,019,584 bytes of it) with not problems I even get as far as the burning beginning stages, but...

From Nero smart start menu:

* select burn image to disc (ok) it opens my nero express menu and my ISO file under "all supported compilations and images", I select the UPDATE_BDPS1_VER160.ISO extracted file and the click "Open" it opens it to the nero express image: (box) as " C:\My Images\UPDATE_BDPS1_VER0160.ISO " and the distination drive screen, when I choose next it tells me my computer compilation cannot be written on this kind of disc. Please insert disc of correct type or modify the settings of your compilation to make it compatible with the current disc.

Why is it not accepting the blank DVD-R as a writable disc for this file?? it's driving me nuts!!

Thanks for any assistance...
