The DVD format is not compatible with Apple TV and can’t be streamed directly via AirPlay. So you have to re-encode it first.
You can do this using VLC Media Player on your PC: http://www.videolan.org/
Go to “File > Open Disc…” in VLC and open your DVD.
Enable AirPlay Mirroring and make sure that you see the VLC window on your TV. Double Click in the video window for fullscreen and start your movie - the video and audio is now streamed to your TV.
Please reply back if you need clarification on any of the above, or even if you just want to say "thank you" :-)
