I'm playing a Tutu game of the same DVD version you have. I installed the international patch TotSC patch for BGI and the English ToB patch for BGII. All of it of Bioware's website, and so far no Issues/Bugs.
If your looking for (easy) tutu patch/mod order let me know, and I'll post it when I get home. I managed to track down an excellent thread on pocket plane (IIRC) all about it, and have it saved on my home computer
