Help adding subtitles/closed captions to DVD

[TomT64]

I have looked on these forums and all over the internet and have found nothing that addresses my specific problem.

I want to add subtitles and/or closed captions to an existing working process of making a DVD from my TV in Windows. My process works like this:

1) I get an NTSC MPG rip from my ReplayTV (a Digital Video Recorder like TiVo, but IMO better). This MPG holds Closed Caption information (for future reference).
2) I edit out the commercials with Ulead VideoStudio 7 SE DVD.
3) Repeat 1 and 2 as needed
4) I make menus on this and any other edited videos with Ulead DVD MovieFactory 2, and output the folder. (I am quite happy with the menus this program creates and if I have to use a new tool I would like one that at least meets the ability to make menus this way or better, I don't HAVE to pay for it, and is not too crippled if it is trialware).
5) I then use IfoEdit to add DVD-Text and I use TMPGEnc to add Jacket Pictures to the folder output.
6) Now I burn with ImgTool Burn.

So this entire process works. Now I want to add subtitles and/or closed captions. I already have a working process for getting the subtitles easily. This is it:

1) I rip the closed captions using SCC_TOOLS' SCC_RIP and CCASDI (-s for subtitles) (although this is a long process for the CPU, at least I know it can be done and I don't have to type out the subtitles).
2) I then sync the subtitles to my edited MPG, with necessary edits, using Subtitle Workshop (so I can already save in many subtitle formats). From here if necessary I can convert to Closed Caption files if I want that.

Now I want to add my subtitles in, but it seems I have to do something very complicated to do this, by demuxing my VIDEO_TS and then remuxing it with subtitles. But I don't want to have to do this. So here's my question:

Is there somewhere in my process I can add subtitles and/or closed captions BEFORE making my folder (even if it means using a different tool)?
*Please also note I cannot use the latest ReelDVD, I have WinXP Home Edition, and I also cannot pay for any tool. Trialware/shareware MAY be acceptable as long as it is not too crippling in its free use.

If there is NOT a way to do that, then is there an EASIER way to add subtitles somewhere else in my process, before I burn it to DVD?

Even if you know of no other way to do it than with demuxing and IfoEdit remuxing I would appreciate a reply.

To the best of my knowledge the only authoring programs that can mux subtitles are: DVD Maestro, Sonic Scenarist, Adobe Encore, Reel DVD and IFOedit.

Since you say you have no money, IFOEdit is your ONLY choice.

There's really no way save re-authroing (ie. re-muxing) to get those subtitles in.

So then my only (free) solution is to author the DVD then demux, then remux with IFOEdit? That's too bad. Is there any trialware that does this? Also what about closed captions?
