Apple TV installation issue

I’ve created the Patchstick without probles with the latest MAC OSX system: 10.5.1.
No problem patching Apple TV. No errors. When rebooting, after the cinema presentation, the menu does not appear. Instead, only ATV logo on the screen. Nothing more. Please heeelp!

This is related to the flash drive you are using. Try using a different brand. Memorex or Kingston work well.
