Well I guess that Nero Drive Speed that I d/l from Brothersoft has something in it that parmenently changed my optical drive firmware (on the Windows side).
It wouldn't have been the firmware, but it could have been a low level driver or something else that interfered with the operation of the drive. Firmware goes on the DVD drive itself. Drivers go on the hard drive. Inland mentioned "Filter drivers."
http://en.wikipedia.org/wiki/Filter_driverThe drive probably came with the older firmware when you bought the computer. And they updated it for you at the Genius bar. Maybe the firmware update was to improve burning capability.
Am considering getting Snow Leopard for $10 tomorrow at the Apple Store, repartitioning my hard drive (after the optical drive is fixed) and wiping out my entire hard drive, installing Snow Leopard, reinstalling Win XP, but have to know more about Snow Leopard regarding will Photoshop CS 3 and ComicLifeDeluxe run ok on it?
I don't think the Mac side would be affected by whatever Brothersoft "add-on" you might have picked up. Not unless you got Mac software from there at some point. You might want to redo your Boot Camp and Windows though.
Since Photoshop CS3 and ComicLifeDeluxe are important to you, you might want to wait until there's more user feedback before installing Snow Leopard. Hopefully if there's a problem, the software manufacturers will update their programs so they'll work.
If you decide to install Snow Leopard, be sure to update your Adobe Flash Player afterwards. Snow Leopard shipped with the older, vulnerable version of Flash Player. There was a mention of it in last week's Security Now episode

You can get the updated Flash Player from the Adobe site
