Dvd video/rom + cross platform

Hello there!

I want to make a DVD with both Rom and Video parts. The Rom part should be readable on Mac and Windows systems, and the video part should be playable on any dvd players, software or hardware. Right now what I do is create a new dvd-video project in Nero 6.6.0.3, put my .vob and .ifo files in the video_ts folder that is created by default, and then I just add my other files in a folder outside the video_ts and audio_ts folders.
This method works fine on my computer (windows os), but I don’t have access to a mac or to hardware dvd player, so I cannot be 100% sure that it’s gonna work elsewhere (and I need to be).
So if you know anything about hybrid dvds compatibility etc…, please share your knowledge!

Bye bye
