I'm authoring a DVD of several videos using TMPGEnc DVD Author. I have 5 tracks, with each track containing several videos. I have a main menu with 5 sub-menus.

When I author, everything works fine off my HDD using Power DVD, however when I burn it to disc, I am having several problems.

First, when playing on my standalones (Panasonic RV31 and Sharp portable), selecting certain items in the menus causes the player to lock up (some items work, others cause the lock-up). Also, I have some macroblocking in several of the videos, although they all play fine off my HDD.

I have tried burning with Copy2DVD and DVD Author's burner, both have similar results. I am using Ritek G04's for media.

Finally, when I put the disc I burned with DVD Author into my Sony DVD-ROM, I am receiving this message:

"DVD-Video playback graph building failed"

Any idea what the problem might be? Is this indicative of a media problem?

Any other info I can provide?

Thanks.
