I know that this topic might be "dead" by now, but it's still a really nice script and the link happens to be dead, so if the author or anyone who got the program could upload it again that would be superb!
You guys (insomnai, sleepydvdr) need to read the File System Redirector part of Programming Guide for 64-bit Windows. Actually, if you think you'll ever do another script for a x64 OS, read the whole guide (especially the Running 32-bit Applications part). This is all really basic if you just check the documentation.
