Any ideas?
Many Thanks!:)

Easy, just use a converter...

I know Moyea FLV to Video Converter on Yahoo answer and use it, really simple and easy-to-use program, maybe you can have a try.

Just google for this tool...if you are interested.

Haha, I found the program by searching "flv to Apple TV". Very good program. Thank you!:)

it's rather easy if you have a flv converter (http://www.leawo.com/flv-converter/), with which you can easily convert a flv to MP4, then play it on apple TV.
