Hi my name is ***** ***** to JustAnswer. I am reviewing your question and will reply ASAP.
You can share the video on sites such as YouTube or Vimeo, and you can make it private unlisted so only your friends and family members can view it with a link that you provide.Did you create the video in other software, before sending to iDVD to create the DVD?
I can help you with the correct settings, I just need to know a bit more about it, like if it was made in iMovie, FCP X first etc..
Please reply here and we can begin preparing the video for uploading, it shouldn't take too long
