HandBrake

If you can open the files in iDVD you should have the option to save them as a disc image, after which you can mount them and they'll appear as a regular DVD to HandBrake. So once I've mounted it and it appears as a regular DVD what actions do I take within HandBrake? Will that convert it to a form...

I have several .DVDPROJ files that contain family videos created with iMovie. I no longer have the source audio and video files, unfortunately.

I would like to convert the .DVDPROJ files to a format that I can upload to YouTube.

Will HandBrake do this? If not, any suggestions?

Thank you kindly
