Query away my friend. I have been playing that backup for a couple days now with no troubles. It is indeed a liteon 166s that I am running my backup from.

I will say this: That post was my second attempt. My first attempt everything was set the same except I read it at 4x instead of 1x. While I was installing the first attempt it would freeze a little over halfway way through the installation (still installing from the first disc), it said that it could not read some file and everytime I tried to 'retry' it wouldn't get any farther. I have been using RiData (Ritek) 48x CD-Rs as my media. I trashed that one, gave up for a day and played from the original disc. The next day I decided to try it again as I don't like being beaten down by a protection! First I uninstalled University and restarted my computer, then I did what I posted above and everything has been working like a charm. No problems whatsoever. The installation of 'The Sims 2' is done from a backup of the CD version of the game. Also, I noticed the initial load time is a few seconds longer than the official disc, but to me that's no biggie.
