Exporting from Moviemaker Problems

I have been having problems exporting a 54 minute, 11Gb project out of Moviemaker, first to DV tape, and cannot get a smoothly running movie. The sound is perfect in my computer, but skips in places on the tape, not always in the same places on different copies. I've tried emptying everything unnecessary out of memory, de-fragging, etc, but nothing helps.

Then, I've tried to save the project to my hard drive, or burn it to CD. No luck. After 6 or 8 hours I get non-specific messages saying that either the memory is full, or the file is missing something, or something else is wrong. Nothing specific. I have a Sony computer with Click to DVD on it, but that won't accept the Moviemaker format.

All the professionals who I've asked laugh when I say I have Windows Moviemaker, and can offer no help.

Any suggestions? Ideally, I'd like to at least get a perfect DV tape, or a DVD, without needing more hardware or software.
