It will only work if the data is uncompressed and unencrypted, and the FMVs are in the standard mpeg format.
BTW: I found a bug yesterday: if a stream doesn't start at offset 0, the first part of the data will not be correct.
You can edit the list file and put a 0 in the offset (the second number), but you will have to remove the extra bytes from the begining (not sure how to write that word).
It's already fixed, but the next beta isn't finished yet. I'm adding some new features
