mp2 to vcd audio ; adding sub-titles ?

[pmcd]

I have a svcd file which has video (mpeg2), audio and there is also a file for subtitles.

After I separate the video and the audio (using bbDemux) how would I convert the audio to vcd (not svcd) standard. At this point I only wnt to manipulate the audio. After the audio gets changed I would then like to joint the 2 (MMT works great for joining). Finally I would like to add a file for subtitles.

The standard says:
VCD 1.1 must cbr mpeg-1, layer II (mp2) at 224 kbps
VCD 2.0 must be mp2 at 128, 192, 224 or 384 kbps

Mplex will mux in sub-title tracks also, I don't know if it's been successfuly done on mac yet.

If I first just want to manipulate the mpa file by turning it into aiff/wave/...and then use MMT to join the fixed audio file together what would I use? That is, what program will manipulate the mma file in order to change it to meet the standards quoted. I know you can use Mplex to handle both the audio and video at once but is there nothing that will just handle the audio alone ? Sorry about all this. It's all seems much more complex than I would have imagined.

Convert MP2 to AIFF
This is very basic, but works. Copy and paste into Script Editor then run. OK to change AIFF to WAVE at bottom of script.

--start script
set this_mp2 to choose file with prompt "Choose MP2 file ot convert:"
tell application "iTunes"
convert this_mp2
quit
end tell
set this_mp3 to choose file with prompt "Choose the new MP3 file: Home/Documents/iTunes/iTunes Music/Unknown Artist/Unknown Album"
set the new_file to choose file name with prompt "Enter a name and choose a location for the new AIFF file:"
tell application "QuickTime Player"
open this_mp3
export movie 1 to new_file as AIFF
quit
end tell
--end script
