Considering the jump from iDVD to Studio pro, business critical. new user

Question

Hi all, I will make this as short and concise as possible. I create DVD's for marketing leave behinds for restaurants, properties, etc. I have a wide range of consumers using a variety of different computers and DVD players playing the disks... and these are my most often complaints and problems I need to resolve, it is business critical, as my companies name and reputation are on the product. Thank you in advance for any help and suggestions.
1. Can I easily bring in movies that I saved and rendered under the "Share" function to the media browser in imovie into DVD Studio pro, without recoding etc, just like I bring the movies into iDVD?
2. MANY times the disks are recoginzed in a PC or a Mac as Video TS and Audio TS files and not as a movie(not autolaunching the DVD PlayeR)... I burn directly from iDVD, and have also tried saving as a Video TS, and burning in Toast under the Create Video DVD (I think its called UDF or something). Will DVD studio pro be more effective at the computer and more recent DVD players just playing the movie, instead of sometimes thinking it is a Data DVD. It is very frustrating, especially that even the mac gets confused and either recognizes it as DATA, or starts playing the movie in the middle.
3. Autoletterboxing is very important to me, as I want the movies to play on full screen TVS with the bars on top and bottom, or on Widescreen TV's with little bars or no bars at all. My biggest problem is with iDVD even in widescreen setting, if the end user at home never set up their DVD player that it is hooked up to a widescreen, it automatically goes into Pan and Scan mode, which really confuses my client. Or vice versa I have used "My DVD Edit" to do auto letterbox, and it causes an opposite effect sometimes stretching and distorting the image on widescreens.
Any tips etc to make my discs perform as close to a traditional movie you would rent at your local video store (and the most compatible settings) would be greatly appreciated. I thank you all, and understand this is a lot to ask of someone for this much help.
I use Verbatim DVD-R's, and have tried varying my burn speed as well. I have my entire business riding on this, and my movies are very simple to produce, but they don't do anyone any good if they don't play.
Thank you!

You're either exaggerating or you're completely off your nut. Your business is based on price, service, and the quality of your products. The promotional piece you leave behind is nothing but a shiny piece of plastic. As Shawn has pointed out, there are only so many things you can expect to learn how to control when producing DVDs and one thing that is totally out of your reach is what your prospects do with your disks.
You will want a good inkjet printer and a huge bulk supply of printable disks. A mutiple disk burner pays for itself within a few days if you are making five to ten copies of any single title.
Before you jump, buy and read carefully the two or three books that are all about DVDSP4. If you know someone who has the FCP Studio suite, buy them dinner and a bottle of wine and ask them to show you how DVDSP4 works. The suite comes with a complete tutorial resource disk for DVDSP4.
