Adding subtitles to a DVD

[RealTelstar]

I'm ripping my dvd-teque of about 100 discs that will go in a HTPC and i want to add some subtitle languages for some movies that are lacking. This will tremendously help some members of my family to enjoy the collection.

I have read two guides, one here and another on cdfreaks, but bot are a very long and tedious process.

OK up to convert the format to sup, but after that, I'm not really into muxing and demuxing
I would like a faster way to do the process and I could buy a commercial application. The saved time is definitely worth the cost. I tried ulead and i liked the interface: would that be enough for my goal?

Note that I don't want to screw any other part of the DVD structure. But I would like to have the additional sub(s) added in the menu or in place of an unneeded language (i.e. spanish).

I use anyDVD to rip to hd and I prefer it to DVD FAB Decrypter (i checked the platinum too) because its easier and has the function to skip to main menu that get rid of the terribly annoying nag screens on most (but not all) discs.

I think I posted in the wrong forum. Reposted in the subtitles forum. Sorry.

I haven't seen any commercial product that let you add subtitles to an existing dvd and you can keep the menus. No ulead can't do it.

It is not that complex but you must demux and remux, https://forum.videohelp.com/topic334315.html#1735346 and if you want add a menu page you could use dvdremake pro.
