How to burn DVD with 2.35:1 ratio

Hi I am new to all this DVD, codec, aspect ratio fundas. I have some movies in divx or xvid format with the aspect ratio of 2:35:1. When I create a move DVD with those files, the option available are aspec ratio 4:3 or 16:9 i.e, maximum 1.78:1. I use either TMPGEnc DVD Author 3 or Ulead Movie DVD Factory 6. Though my TV does not support widescreen view at present. I plan to write the DVD with aspection 2.35:1 so that in future I will not miss the real theatre experience. I want some guidance from experts and senior members.

The DVD spec only supports 4:3 and 16:9. Films presented at 2.35:1 on DVD are all letterboxed, usually to 16:9.

I downloaded those movies from internet..

If it's a PAL DVD: Resize the video to 720*432, then add borders top and bottom of 72 pixels each. If it's an NTSC DVD: Resize the video to 720*368, then add borders top and bottom of 56 pixels each. I know both these instructions aren't exactly 2.35:1, but they are mod 8.

Well, MPEG2 itself supports a 2.21:1 anamorphic feature, but the DVD spec does not. Interestingly though, I once tried this by removing the 16x9 letterbox from a 2.35:1 movie, and padding it to conform to 2.21:1. After a resize to 720x480, and setting the 2.21:1 flag, it actually did playback in my old Cyberhome DVD player... Can't say this would work in every player, especially the ones that are strict in compliance.

what did you author the disc with? i don't know of any authoring tools that wouldn't reject such a stream (or just reflag it to 4:3 or 16:9 depending on what's set for that timeline) unless your authoring program ignores mpeg stream flags, and your player happens to read it's aspect info from the stream rather than the IFO... this has been known to happen on certain players, and certainly Spruce doesn't touch the aspect headers for 4:3 or 16:9, but it's a worry that it doesn't at least spit a noncompliant stream. i must has to be doing some testing now :) but it's not at all useful of course, unless you can master your own 2.35:1 films rather than transcode (as it happens i can do this :), but finding a 35mm print of my favourite movies is another matter, as is legality of course).
