iDVD and MPEG 2

Hello everyone,

I'm trying to burn some MP4 files onto DVDs that I can play on the DVD players in my house. I've been told MPEG 2 is the format I'd have to use to get this to work. I was also told that if I burned the DVDs using iDVD it would automatically convert the MP4 files to MPEG 2 for the DVD, is that right?

Alright, I got the file onto a DVD, but when I play it the video quality seems a little lacking and the audio is out of sync. How can I fix these things?

As you found out, iDVD does the conversion to MPEG2 along with the audio.

You have to supply it a quality product. For instance, if the size of the original is smaller than 640x480 then the expansion will affect the picture.

I've only done a few iDVD creations and never used MP4 files, so am unsure if the sync problem has anything to do with that. Its been a while, but, I likely used QuickTime .mov files using the AIC codec with PCM audio.

As a side note, recently my brother played a homemade DVD in a DVD player and his new Blu-Ray player. The audio was in sync in the DVD but out of sync in the Blu-Ray machine. Weird.
