Adding Switchable Subtitles

[Equus]

Hiyas:

OK I have a wedding video that I've finished in iMovie. I love everything I've done with it in iMovie and the menus and chapters in iDVD. What I'm not capable of with those two programs is making and adding a true (toggleable) subtitle track. I'm wondering if anyone can advise how to do that with any of the following tools I have on my iBook G4 800mhz:

iMovie/iDVD '05
FFmpegX
MacTheRipper
DVD2OneX
Sizzle
Toast Titanium 6
DVD Studio Pro 1.5
DVDSP Subtitle Editor
MPGTX

I don't want to go through the tedium of trying to create the whole DVD from scratch in DVDSP unless someone can tell me how to a) use one of the animated menus from iDVD in DVDSP and b) send the movie from iMovie to DVDSP without losing quality.

Otherwise, is there anyway to create the movie in iMovie, use iDVD's menus, create a subtitle in DVDSP and then author them all together using DVD2One or FFmpegX, while keeping the menus and chapters?

Sounds crazy, but that's me!

If you can accept some limitations in menus against iDVD Themes, Moviegate 2.0 --freeware for time beeing -- does the job (from iMovie keeping chapters, or from already encoded MPEG2 tracks).

MovieGate looks pretty cool but as you say it can't use iDVD menus. Looks like it does much the same thing that Sizzle does. Can't do a motion menu (video menu) in MovieGate that I can see...

On another note, what filetype are subtitle files supposed to be? I made a test one in DVDSP and it saved it as a .spu file. But neither Sizzle nor MovieGate will allow me to import that.

From Moviegate manual:

"accepted subtitles: .sub, .srt, .ssa, .smi, .rt, .txt, .aqt, .jss, .js, .ass"

Note that i only used .srt (no idea what the others are). They also speak about a subtitle creation tool named TitleLab.

I agree that Moviegate looks similar to Sizzle (with encoding capabilities added), BUT most of the DVDs I authored with Sizzle have the bad habit to be playable only on a limited number of DVD players. This does not apply to Moviegate authored ones.
