different compression methods used for these modes; I assume they're
just quick-and-dirty things like reducing the pixel and colour
resolution?
The Bit Rate.
Er.. yes, it can quickly calculate the bit-rate limit based on 4.77GB and the number of hours required, but my question is, how does it achieve that bit rate? I'm assuming there's some standard algorithm which all such devices adopt...
Yes. Its called MPEG-2.
