ATV wont boot from USB stick

I am using a crucial usb 1G stick, running 10.6 on macbook pro. I have tried several of the solutions listed in the older posts. Downloaded the newest atv flash. this is my first try to update Atv.

ATV boots up normally without patching.

I have noticed that while transferring data to the usb stick the display counts to about 33% then jumps to converting to apple TV format.

I would appreciate any help I can get.

Thanks
Mike

Got it! I saw the PSP post and decided to try my compact flash card reader and a 4GB card. Bingo it worked.
