Can I use an external hard drive instead of a flash drive??

I have an external hard drive which is formatted in Mac OS Extended (Journaled) format. My question is can I use this hard drive to install ATV Flash on my apple tv or am I limited to using a USB flash drive?

Yes, any drive about 256mb in size should work. Please note, any information currently on the drive will be erased.

What about using my old mp3 player?

It’s possible. Some people are using iPod Shuffles.
