SVCD subtitles... how?

Hi, I recently purchased a DVD player that is SVCD capable including subtitles. My previous one didn't shown subtitles, so I never care about it, but now I do. I usually encode SVCD's with DVD2SVCD, but I like to split the final mpeg's by hand in order to put cut points in scene changes, something DVD2SVCD doesn't do. But of course, things get more involved when you want to include subtitles, and I'm all messed up. So I use DVD2SVCD to encode video and 2 audio tracks (spanish and english), and so end up with two .mpa files and one .mpv. Also DVD2SVCD rips subtitles from the DVD. Having all this, could somebody explain how can I cut video, audio and subs in 2 or 3 parts (corresponding to 2 or 3 CD's), mux everypart and end up with 2 or 3 CD's with the video, the 2 audios and the subs? Thanks...

How I do... 

First I mux video + audio with bbmpg and cutting it at the desired point. Then I rip the suptitles with subrip and SPLIT the sub file with the same program. You can do it before saving it to hard disk. Bonzo.
