and saved it as a microsoft dv-avi file which i was about to put on dvd when i discovered that it was 11.5GB"
when u save a video file thats raw and uncompressed it will be very large. the dvds from the rental store are dual layer discs and will hold around 9 gigs. the dvd format is a compressed format usually mpeg 2

i dont know how a video file can take so much memory as a normal dvd file only takes 700mb any help would be appriciated."
i think you mean a vcd for 700 mb and thats usually a heavily compressed dvd file to fit into 700megs.
try two programs dvd shrink and dvd decryptor.
