Friggin' awesome.  You are a machine!

Here are my comments:

Chronomaster:
"  0070    apparently a palette chunk, 0x300 (768) bytes, and each
           component is 8 bits (not 6 bits, like VGA palettes are
           normally stored)"

Actually, if you used VESA, it would indeed take and display properly an 8-bit 
palette.  If the game loaded Scitech's Display Doctor automatically, that was 
a good chance it relied on VESA to handle the video.  Since it costs nothing 
to store the actual 8-bit palette (you just SHR 2 if you use real VGA palette 
registers), I think many if not most companies did this.  I sure did.

Novastorm:

"
   sample rate = 256 - (100000 / (signed) divisor byte)

   0xC1 = -63

   sample rate = 256 - (1000000 / -63) = 16129 Hz
"

Hold it, which one is the right forumla?

Tsunami:

"The media frames follow the header. Each frame is packaged inside a
chunk with the fourcc 'IVAS' (probably I. Video & Sound, where 'I' is
presumably the same 'I' in 'BF&I'). "

Actually, the I is most likely "interleaved", as in "Interleaved Video and Sound".
