The closed captions (when present) are part of the AC-3 audio stream in the broadcast, so you'd have to look for support in the code which deals with that.

I have recorded a program with the pchdtv card and viewed the closed captions as a test, but most linux users wouldn't want to do it the way I did. Apple provides a sample program for Macs running OS X which allows a Mac to act as a Firewire D-VHS recorder. Using that program, the Mac can play back an m2t file (MPEG-2 transport stream) through Firewire. I recorded a program using dtvstream to make an m2t file, and transferred the file to my Mac. I was then able to playback the file using the D-VHS program to a Samsung SIR-T165 tuner (with Firewire input). By selecting closed captions in the T165's menus I was able to view them.

These are only available on some stations (one in NYC), but I've been working on support for them in MythTV. If you want it to work you should try the hdtv-recorder-v8.tbz patch at http://www.mrl.nyu.edu/~danielk/mythtv. and send the output requested on that page.
