Sigh. Yeah, ok. If you really want the play-by-play:

1.) I start watching livetv (or a recording).
2.) I bring up the menu
3.) I moved down to the closed captioning line
4.) I click my OK button on my hauppauge remote over the "toggle cc"
5.) It doesn't work. Nothing changes. No closed captioning.

Gee, I guess you didn't need the play-by-play after all. :(

Asinine comments aside, how come closed-captioning isn't supported on
the PVR-x50's? Is it a driver issue (in other words, is the ivtv driver
incapable of processing closed captioning), or is it just that mythtv
needs some work to integrate with closed captioning support in the ivtv

Also, what about commercial detection? Is that supposed to work with
PVR-x50's, or not? If it is, then I'd love to figure out what I need
to change to make it work on my system.
