Ok, heres the deal.

I am in an apartment with a few guys, we happen to have 2 X360's between us.  I am playing Bioshock and am getting quite far, BUT the game keeps skipping and it is becoming more frequent.  I am wondering if there is an easier way to transfer the game saves to the OTHER X360 to see if that will make a difference rather than having to go buy a memory card.

OR

is there a known problem with early copies of Bioshock and is there an answer for that?

Thanks for the help, I looked around the forum as much as I could to try to find an answer before posting.

PS. We are for some reason restricted to Xbox Live, I've done all I can, so I am unable to update until I get a chance to get on another network.
