Direct DVD Playback from Windows 7 PC to Apple TV 2

Hi, I’ve been trying to get the direct DVD playback working using my Apple TV 2 and my Windows 7 PC
I’ve shared the DVD drive on the PC and when I enter Media>My Files i see the DVD player and other shares. The Metadata is then found for my DVD, however when i try to play the DVD I get the Playback error message.
I should say that other shares to media files work great
Any help will be great

Unfortunately streaming directly from the optical drive is not currently supported, but may be added in a future version.
