    Therefore to clarify:
    • You may not discuss breaking DVD or BluRay encryption, copying, or "ripping" commercial, copy-protected DVDs.
    • This includes DVDs or BluRays you own. Even if you own the DVD or BluRay, it is still technically illegal under the DMCA to break the encryption. While some may argue otherwise, until the law is rewritten or the US Supreme Court strikes it down, we will adhere to the current intent of the law.
    • You may discuss ripping or copying unprotected movies or homemade DVDs.
    • You may discuss ripping or copying tools in the context that they are used for legal purposes as outlined in this post.

I have burned a lot of movies in idvd that I have made in imovie,so I feel I know how to do it. The last few times I have gotten a multiplexing error at the very end.The movies are about an hour and a half,same as I always make, they go thru all the bullets get to last bullet burn,it says multiplexing & burning, has a picture of a disc on the right & with just a few minutes to go the multiplexing error comes up & all is lost!!
If anyone has any suggestions I sure would appreciate it!
Thanks,Sylvia

In my experience, this generally happens when the boot drive is starting to get full.

Though they don't mention this ANYWHERE, iDVD and other such dvd-burning programs need a HUGE amount of free space in order to operate properly. As a rule of thumb if you're going to be burning DVDs you should have at least 12GB (yes, three times what the DVD can hold!) available before starting. In the case of iDVD I'd be even more generous and allow 15-20GB.

By coincidence (not), I generally recommend keeping 12-20GB free at all times even if you're not burning DVDs.

If your drive is not full, here's another suggestion: uncheck "put drives to sleep when possible" and all other energy-saving measures in Energy Saver (system preferences) when multiplexing a DVD.
