I'm with Aussie14 on this one. Are you doing all of these transfers from XboX DVD to PC via FTP and then from PC to XboX Hard Drive via FTP just to get them copied? Cuz if you are then for goodness sakes get boXplorer, HDDLoader, XBCopy, XB Commander or something. You can and should use them to copy straight from the DVD to the Hard Drive. The only reason you should be copying them to the PC is if you want to share them or burn a DVD of them and the only reason you should really be copying them from the PC is if you got them off of newsgroups or if its a homebrew...
Just my $.02,
