can you copy xbox games?

[Tom Savini]

One quick (well...) question;
I have seen many people talking about transfer the game from the xbox to the PC with "flash XP". Does it have to be that program, or is a "normal" ftp ok ?
I did use a normal FTP program, it works nice (so far, only one problem).
Have made backups of some games with ordinary ftp, and burned them. Now, the first problem has accured.
When playing Desertstrike in the sewers (level 9 or so?) the game stops. Tried a couple of times. Hangs each time.

Could it be that I don't use flash xp ? Sounds strange though.

Another strange thing (maybe I'm too newbie); why ISO's ? I did atransfer to the PC HD and burned on a CD-R or sendt back to the Xbox HD. No problem. Kept the games on the PC, kept it in RAR to save space. Why ISO ? It takes longer time to extract etc., I can't se the advantages ?
