There are 3 ways a DVD can have forced subs. 1) embedded in the video (e.g. Lord of the Rings) in which case you don't have to do anything special, 2) they are in a separate forced subtitle track (e.g. Star Wars Episode 4... greedo scene) and 3) they are embedded in the normal subtitle track (don't have an example that does it this way).
For 2), you would have to figure out which subtitle track it is and rip it. This involves trial and error although the forced subtitle track will usually be much smaller than the others. When using DVD Shrink, you would want to tell it to always display that track or else you would probably have to manually tell your movie playback program to display it. To do this, when you drag the main title over to the left-hand side (when re-authoring to only select the main title track), right-click on the title and select "Set Default Streams". Go to "Dispay the following subpicture stream" and pick the forced subtitle track (this is where you set the default audio track as well if you ever want to do that). If you don't do this, I'm not sure if your movie player has a way to know which track is the forced subtitle track and thus, if it can automatically play it or not... I could be completely wrong though. This is how I've been doing it for a few years now.
I don't know how to do 3) as I've yet to encounter a DVD that does it that way. Can't help with clown BD either as I use eac3to + bdsup2sub + mkvmerge.
