Sony BDPS-350 - firmware update

[wombat7477]

Hey. New here. Thanks in advance for the help.

I have a Sony BDP S-350 player. Has been working great, but will not read Eagle Eye. Checked firmware, and I have 7.1.007.

A direct ethernet connection is very inconvenient (major hassle to run the cable). So I opted for the update disc. I downloaded the .exe file, which produced a .iso file. I confirmed the file was the correct size per Sony's website, so the download seems to be clean.

I used Astroburn to burn the image to a CD-R, and that also seemed successful. But my player will not read it. I tried twice, no luck. The only potential problem I see is that Astroburn didn't seem to give me an option to 'finalize' the burn, which Sony's site recommended. I wonder if this might be the problem.

Sony's online chat support was weak.

Anybody have an idea? Or know how to finalize the burn with Astroburn? Or can recommend a different image burning software?
