Using RMC 4.4.3.0 can't convert MFC streams to any other format?

[noviceuser]

I am recording MFC streams using Replay Media Catcher 4.4

I want to edit the videos, but I cannot for the life of me get them to be anything other than the original files.

If I drop them in Freemake video converter for example, the output file is an out of sync, stuttering video, slow motion mess.

I tried FIXFLV using RMC, but it does nothing.

Is there any way to take these (I assume VBR) FLV files, and convert them to an iMovie friendly MP4?

I am willing to pay someone to help me get the process done.

Thanks.
