720×480 with a 1.2 (1.185) pixel aspect ratio would be the correct size for 16:9 video on a DVD.
Also see the Adobe TechDoc Work with non-square pixels… -
Erick,
As eric mentioned, copy protection can only be added to replicated DVDs. Replication means pressing discs from a glass master. Normally a replication run starts from at least 300 discs.

Even if you are using uncompressed AIFF audio with that, a maximum MPEG-2 bit rate of 5Mb/s should put you way below the allowed limit of 9.8Mb/s.
Are you sure that it was the maximum which you set to 5Mb/s? What is the total duration of all video in your project?
A possible quick fix could be to use A.Pack to convert the audio to Dolby Digital (AC3) at 192 or 224Kb/s. Assuming that you haven’t done that already, this would lower the total bit rate by well over 1Mb/s.

Not really. The only “sort of” copy protection for writable DVDs is to burn your project to a DVD-RW that supports CPRM (Content Protection for Recordable Media) and burn DVD-R copies from this DVD-RW master. This seems to make copying a bit harder.
Also see the DVD Demystified FAQ: What are the copy protection issues?

[Erick] “…since the new version of Sony DVD has a feature where you can apply macrovision to your DVDs…”
Erick,
Could you please give a link to information about this feature? I find it very hard to believe that any DVD burner or recorder could do this.

Depends on what you mean by “button”. 🙂 A button as an image that will (eventually) by merged into the background image can use 24 bit color and thus a gradient as well. The subpicture highlight part of a button on the other hand is limited to a maximum of 3 colors. (Technically 4, but one color is used for the fully transparent background of the highlight layer.) That means that gradients can only be simulated at best, using dithering and careful use of opacity settings.
A video tutorial on subpicture highlighting, Highlight Colors – The Low-Down on Subpictures, can be found at adobeevangelists.com: Adobe Encore DVD.

The bit rate is rather high and as it is VBR it will go even higher than 8Mb/s. Is your client perhaps using a laptop computer to play the DVD?

It isn’t a chapter stop, but a chapter marker or chapter point. As it is just the same as any other chapter marker you would add to a timeline, I don’t see how it could introduce a delay in returning to the menu.

If the Digital Rapids writes a PCM file with .pcm extension it is most likely a “raw PCM” file instead of a “PCM WAV” file. Encore, like most other applications, will accept only the .wav variety which not only has a different extension, but also a different structure.
Failing an option to write a real .wav file directly, you could check the “Tools” section at VideoHelp for a utility to convert from .pcm to .wav. Such a conversion will be lossless.

Most set top DVD players will hold the last frame or field while they are searching for the start of the next item to play. My guess is that this is what you are seeing. It is an inevitable side effect of linking timelines.
