I have no idea what happened, but suddenly Movie Maker refuses to save anything above 800kbps. I had my previous specific settings good to go, and it was working fine. I haven't used it for about six months, and now when I save things - whether it's on my custom setting or on the maker's high def settings, it won't save to those specifications. A 2 GB video that I shave off a minute or two in trimming will save as a 158 MB file. It's extremely annoying and I have zero idea why it's doing this or how to fix it.
