ٔRe-Import Closed Captions(CC) to DVD

Hi, All!
The DVD which I work on has 2 subtitles & 1 Closed Captions. I want just add 3rd Subtitle to DVD and dont delete other Subtitles & Closed Captions.
When demux DVD, CC dont demux. Of course, I can demux it with VobSub Configure (in 3 format: raw, srt, unicode.srt)

I wonder that when I remux DVD with MuxMan, how and which one of 3 format of CC should be given to MuxMan.

Another Q: Are CCs textual or geraphical?

Closed Captioning is textual and embedded in the video stream as user data. The data should still be there after demuxing.

Explain more.
I demux DVD with PgcDemux to *.m2v, *.ac3, *.sup
You say m2v file contain CC, too?

Also, I extract (raw, srt, unicode.srt) of CC with VobSub.
Now, I want to remux these with a Authoring tool (e.g. MuxMan).

What about CC files? Should I extract CC with another method?
Accept MuxMan a CC file? How and which format?

If you're not married to the way ccaptions work, a wonderful solution is to use an app called ccExtractor (freeware) to convert the closed captions to an .srt file. From there you can do whatever you want with them.

Yes, the m2v file contains the original CC. If you want to change it with an external program and remux with MuxMan you will have to add it back to the m2v with a program like McPoodles CC_Mux Other programs accept SCC format. srt is NOT a CC format, but a subpicture format.

Converting CC to srt format is used to change CC to subpictures (aka subtitles) which do not require a display device capable of decoding CC. If this is your objective, MuxMan accepts SST (which uses accompanying bmp files), sup, or sp files.
