Prmiere CS4 / Encore HD(footage) on dvd4.7gb problems

Question

Hi guys!
I like to create a nice custom build dvd (standard dvdR 4.7gb ) with menus and transitions from my recorded video clips (" AVCHD Video (.mts) ") with my JVC camera. i know how to work in encore cs4 and premiere pro cs4. the only thing i dont know is what formats to use and resulution so i will not loose any of my hd quality.
Can i use my HD footage from my camera ( those .mts files), and have them pre-rendered with premiere pro as .m2v files and import them to Encore so i can build my project and play them on my dvd player on tv without loosing any quality?
Can anyone help me out telling my i can do best and why? so i have more understanding of how to keep the same quality of my " AVCHD Video (.mts) " files or atleast a very high quality for my DVD4.7gb dvds if HD is not possible.

Answer 1

You have several options;

1. To keep it in highest quality you will have to burn it to BluRay (BR), which means a BR burner and a BR player
If you do not have a hdtv and a standalone BR player you can play your BR on pc (e.g. Power DVD) or Playstation.
[/quote]  This is minor issue at the moment, but in the future i will surely buy one .

2. Burn your movie to DVD in HD quality. This means you make a BR iso (fully authored with a menu) and burn it to DVD with e.g. Nero.
You do not need a burner just a player: either pc, or standalone. About 20 minutes movie length on a SL and about double on a double layer although not all players like DL.

3. You burn your movie in SD to DVD. Downscaling of the HD footage either in Premiere or in Encore.
[/quote] this is actually what i did Ann, i scaled the origional footage (*.mts ) in my "DV Ntsc(720x480)widescreen" sequence in premiere  and then EXPORT Media and have Adobe Media Encoder render it out as m2v files with i supose the same quality, but i guess here is the problem were it went wrong. im not sure though.
doest is matter what sequence type i choose and if so whats the best one for my AVCHD footage?
i set my sequence to "DV Ntsc(720x480)widescreen"  coz i know that a dvd , standard-definition video needs to be :
Frame rates and sizes for standard-definition video formats are as follows.
Standard
NTSC
PAL
Frame rate (frames per second)
29.97
23.976*
23.978*
24*
25
Frame size (pixels)
720 x 480
720 x 486
704 x 480
720 x 576
704 x 576
Frame rates and sizes for standard-definition video formats are as follows.
so i choose the in green displayed formats for my widescreen dvd, thats correct right ?
