Converting SRT with colour information

[boulder2]

Hi, I was wondering.
I have this program which rips Teletext subtitles from TV shows.
These subtitles make heavy usage of colours (sometimes 3 colours on screen simultaneously).
Therefore I chose SRT with colour tags as a format.
Now, suppose I want to burn the TV show with the subtitles to a DVD.
Are there any programs that can handle the colour tags, and don't lose the colour information when burning to DVD ?

An example of a couple of lines of an SRT with colour information :

1
00:00:03,300 --> 00:00:04,200

Hi,

The problem with DVDs is that it is not easy to use multi-colors because only 4 colors are authorized locally. One of them is the background and one the outline. This leaves us with 2 colors. But most of the free authoring programs use one of the colors for anti-aliasing which leaves us with one color only.
Another solution is to use different colors for different areas (the DVD specs allows for 16 different areas per subpic). To my knowledge, of the existing free authoring progs, only SubtitleCreator uses this trick. It currently only allows for 1 extra color per subpic using the <k>this is the text</k> tag (i.e. karaoke).
Maybe the professional tools offer other possibilities

Ah, I see.
It 's a bit strange though that Teletext, which is '70s technology allows or more colours than DVD's :)
So I guess people who want to burn to DVD will simply have to find other ways of representing the different characters speaking.

Two more questions :

1) Do HD-DVD and Blueray still have these limitations ?
2) Suppose instead of converting to SRT one would use DVD closed captions, would that make a difference ?

I think it's because the authors of the DVD specs wanted to compress the DVD subtitle stream as much as possible keeping a good quality.
As I explained above it is actually possible to use different colors per area on the subpic but the software implementation of these if not very easy which explains why no open-source software implement it fully yet.

Do HD-DVD and Blueray still have these limitations ?
Yes but instead of being limited to 4 colors they are limited to 256 colors. :p

About the DVD caption, I don't know.
