I had problem burning good FC3 CDs from the bittorrent images in FC2 before the upgrade. I ended up using Windows XP Pro to burn the CDs.

I had various troubles with an "upgrade from FC2 to FC3 on my workstation. Most of the problems were gone when I later did a full install.

Everything seems to be polished and working wonderfully now, with a few exceptions: My graphics is slow (I have a nVIDIA GeForce 4MX), and I still can't burn good FC3 CDs.
