convert mkv with mutiple subs to mpg2

[choirislife923]

I have a MKV file with two soft coded subs (rendered in player, not permanent) that are displayed simultaneously...one on the top, one on the bottom (bottom for main dialog, top for clarity due to differences in culture). Is there a program I can use to convert the MKV file to a DVD compatible MPEG-2 program stream that does not overlap the subtitles while displaying them both?

mkvextract everything and then convert....with for example convertxtodvd.

or try avi2dvd, it claims to support mkv...but don't know if subs are supported.

nah, i tried loading it in...it couldn't even detect the audio, let alone the subtitles.

i'll try the convertx method once i get back to my pc..

alright, convertx kept on rejecting my subtitle files...anywho, after some trial and error, this is what i did:

1) demuxed AAC audio/XviD video/subtitles using mkvextract (cause vdubmod can't properly demux MKVs)
2) ran AAC through Quicktime/iTunes set to export as 48khz 16bit stereo PCM WAVE
3) loaded XviD into VdubMod, used the TextSub filter and loaded the subtitle (it turns out that vdub made an error and the subs were exactly the same thing (not what i thought), one in UTF-8, and one .ASS)...hardcoded it into the video/frameserved to Mainconcept mpeg encoder to get the MPEG-2 video file
4) loaded the wave into sony vegas and rendered it as a stereo AC3 file at 192kbps
5) loaded TMPGEnc and muxed the AC3 and MPEG-2 together to make the program stream.

theres probably an easier way, but i liked having control of every single step...and it worked out in the end.
