yeah thats the sort of thing. I'm trying to figure out which formats do what and which ones I can strip or compress or re-encode etc. Bit of a new thing for me and it seems to be one of the black arts at the moment and I can't find much on it.
In the meantime I discovered a cheap and nasty way of doing it... just download a version from the web, they seem to be compressed enuff to fit on a DVD-5 disk
My copy of Halo 2 is 5 GB but the downloaded version is 4.3 GB.
It would be nice to do it myself tho.
