The exact same size of the same movies produced by different programs
can be explained easier. Citation: "One other type of chunk that is
commonly encountered in an AVI chunk is the padding or JUNK chunk (so
named because its chunk identifier is JUNK). This chunk is used to pad
data out to specific boundaries (for example, CD-ROMs use 2048-byte
boundaries)". You can notice that every AVI file has the size
divisible by 2048. So, different copies of the same movie just have
the larger or smaller JUNK chunk than the others.

Maybe so. And maybe they used VD to compress video and then used some
other program to mux video and audio. And that unknown program don't
replace existent AVI chunk with it's name.

I don't think so. All videos of LS Studio have AVI chunk with
information that they were produced by VirtualDub (builds can differ).

Do you think LS specially used non-freeware software in order to
protect their pictures and videos from falsification?
