To prove the OP wrong I decided to check out how to unpack the mview file. With zero previous knowledge about the format I checked the link shakotay2 provided and it was in fact quite helpful.
I then proceeded to write a parser and converter in about 30 minutes. This proved that the OP was completely ignorant for saying shakotay2's link was useless.
So, here are the scripts I wrote for unpacking the mview files: DOWNLOAD SCRIPT & NOESIS PLUGIN.
Others might find it useful as I don't have any use for it.
Cheers!
EDIT: A Noesis plugin is also available:
