In the past month I have received several e-mails regarding my CC_MUX tool to insert closed captions into MPEG files. Frankly, the tool isn't even close to working. I am a Perl programmer at heart, but this tool could not possibly run under such a slow language, so I've tried to convert it over to C++. Unfortunately, I've found that getting CC_MUX to work and work efficiently is far beyond my skills. If anyone out there has the time to aid (the admittedly small) community of DVD closed caption authorers by taking over this project, we would sincerely appreciate it.

P.S. If anyone is interested, the full specification of CC_MUX is posted here (http://www.geocities.com/mcpoodle43/SCC_TOOLS/DOCS/CC_MUX.HTML), and my source code is here (http://www.geocities.com/mcpoodle43/SCC_TOOLS/cc_mux.zip). There is one "gotcha" not covered by that page--the number of closed caption frames per GOP is not equal to the GOP size, but rather to the number of frames displayed per GOP. This matters for 24 fps video being displayed at 29.97 fps.
