So when I resurrected the iDVD project, iMovie files, music, etc.
Did you make any edits to the project before trying to reburn it? If so that creates a problem with iDVD preventing a successful encode. It's best to start over with a new project and add the media, i.e. movies, stills, etc., again.
Then follow this workflow to help ensure the best quality final product:
Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image menu option. This will separate the encoding process from the burn process.
To check the encoding mount the disk image and launch DVD Player and play it. If it plays OK with DVD Player the encoding was good.
Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality. Always use top quality media: Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.
Will the DVD disk play on your Mac with DVD Player? Sometimes the Mac is more forgiving than set top DVD players. If you can try to create a disk image of the DVD disk with Disk Utiltiy. If you can then play it with DVD Player to make sure it plays thru completely. If that's successfull then you can burn a new disk with Disk Utility.
Thanks for that advice!
My Mac DVD player did play it through once (so I was excited to play it for my family), then when trying to play it again it died - super sensitive DVDs...
Anywho, one issue with bringing the project back from my external hard drive is that I can't find the iMovie project anymore. I found the file labeled with .rcproject however when I open it nothing happens. Any hints for this?
