Can anyone recommend software where I can insert user data into the mpeg2 stream. I'd like to be able to insert closed caption info the mpeg2 and have a (S)VCD that can have this info be decoded into closed caption info on playback (Many MPG decoders can do this). Any ideas?

Also, I am looking for some authoring software that might be able to add overlay test graphics (OTG) to my SVCD. I'm pretty sure that I-Author deluxe can do this, but unfortunately I don't have the few thousand to spend right now Are there any other authoring products that can do this? Again, I appreciate any suggestions out there. Does anyone have good experiences adding OTG to SVCD?

Thanks a million.
