I have a problem to set a 16x9 video in scenarist to pan and scan! How can you make it (pan and scan) and wide only but I don't want it to be letterbox!

Uh, you have very deep trouble!
Pan&Scan feature is a ENCODING feature, so, if your coder (software or hardware) do not put in to the MPEG2 file information about pan&Scan, Scenarist do not permit you to change this. DVD Maestro can change this setting, but it is very dangerous: some player can display erroneus part of image!
To solve this problem, I wrote a utility to add Pan&Scan information in Mpeg2 files, but only to center the image. True pan&scan permit frame by frame basis to "pan" to see the true important part of view. This part of my utility is under develope.

By the way, I’m wondering how can I find out if a player is set to wide or 4:3. The scenario is that I want to author two menus, one 16:9 and the other 4:3. Both are for the same program. I just want to read how the player is set and jump to the appropriate menu. If I remember correctly, you posted a question about this long before! Do you know how it is possible? I think that SPRM 14 gives the configurations but depending on the aspect ratio of the playing file and also the player, I get different values. I have gotten 3072 and 0 for wide. 3328 and 256 for pan and scan. 3840, 3584 and 512 for letterbox and finally 0 for 4:3. Do you have any simpler solution?

You remember right, but nobody send me a solution. The players I have do different results at the same setting, so, I don't know how solve the problem. But you can set a different hilite for 4:3, lb or p&s, If it is useful.

Yes, but I want different backgrounds too. I will try to work on this and see what happens!

Yaaaaaahhhhhoooooooo. I just found the solution. :D I put all the numbers in front of me and started to think and baaammm, I had a flash of light! You have to check if SPRM 14 is modulo 1024. If it is, the player is set to 16:9, if it is not, it is set to 4:3. I tried it and it works! At least in Scenarist simulation. Tomorrow I will also burn a DVD-R.

I've tried this nifty "SPRM sniffing" thing in the past too. Lately I've abandoned it in favor of setting 1st play to a menu with 2 choices "normal" or "widescreen".

Only some bits of sprm14 is useful, so, I thin your soloution is good, but... All work in scenarist simulation, not in "real life". I have a Toshiba player, and data in sprm14 is DIFFERENT from others player, also with bitwise extraction. May be I need to read sprm14 at very first time, at pre of first play. Now i try with some DVD-RW
