Downloadable Content/Patches

[Robdog007]

I've been on the fence about getting a mod chip for my Xbox, and I think I'm going to take the plunge in the next few days. Either that or I'm just going to buy Fable and let that be the last of my Xbox gaming experience. Anyhow, I'm curious if it is possible to download content from Live using a backup or while playing off the hd. My guess is that patching/extra content is not going to happen with games unless I have the original disc, correct? If it makes a difference, I'm planning on getting the X-chip. (Anyone think I should steer clear of this chip?)
