I recently switched from Windows XP Home Edition to Windows XP Professional. While on Windows XP Home Edition, I used a DVD making software to make a video file into a VIDEO_TS folder and an AUDIO_TS folder. I then used Imgburn to compile the two folders into an ISO and then burnt it. I used this technique hundreds of times with not the slightest problem. Now, Imgburn is suddenly extremely slow to build and burn.
P.S. Slow meaning less than 1.0x and I am still using the same media(not that it would matter because it builds ISO images slow too).
Will post a log asap.
