I've downloaded a game on demand game which is 6GB I done one last week and it took about 10 hours to transfer, is there any quicker way?
only if you have a jtag. if not i haven't found any quick ways to transfer big files to the xbox other than the usual 360Rev, xplorer360, xport, horizon, modio methods.
Won't change much. For me personally it is quicker for me to download a game to my HDD off of XBL than it is to transfer from my PC to the HDD.
