I may have found a solution. I had just come on the same problem. Was playing the no CD version and came upon the movie that plays that causes it to freeze up. Purchased the GOG version that I found a few days ago.
After the crashed I checked the save folder, there were two folders. My main save which I'll call 'DD' and another 'DD.tmp' folder that was created during saving. I just copied the files into the main folder and all seems to be fixed.
Hope that helps anyone that comes across this problem.
Edit: As of yet not a solution. I tested it out and found that the items.000 file is causing the crashes. When I copied the temp data over, it's an empty file and all items (ie weapons, armor) have no stats. Still seeing what I can make of it though.
