DVD/data hybrid disc?

Basically, we need to create a DVD that will:

1. Play in a standard consumer DVD player
2. Play on a computer with the ability to link to websites/email addresses within the DVD menu

What approaches/softwares will best accomplish authoring a disc with these capabilities? We have Macromedia Director MX 2004 and will buy Director 11 if need be. We have Adobe Encore CS3, which we would like to avoid because its design capabilities seem limited.

We have a Sony demo disc here which does what we're looking to do. The disc has video and audio TS folders in its root, as well as what appears to be director 11 files.

Is it possible to create a disc that plays as a DVD (using the video and audio TS folders) when put in a dvd player, but plays as a data disc (launches director .exe) when put in a computer? In this scenario, the DVD version would contain no email/website links, but the director .exe for computer playback would contain these links.

If this is possible, does director 11 have this capability? Do I need additional plugins to author the disc in this way?

Thanks in advance.
