OT: Windows Movie Maker help.

This was my first time using Movie Maker really, everything has worked fine till now, some parts of the 12 minute and 30 second video freeze for around 30 seconds and then continue where it's supposed to, I can't present anything like this and I can't figure out the problem. Respond ASAP.

Thanks.

Arbaz.

P.S. IT ONLY HAPPENS WHEN I PUBLISH IT.
