In MythTV 0.18.1, ivtv 0.4.0 (SBE/FE,-350) and itvtv 0.4.1-r1 (MBE,-250): I just enabled VBI/NTSC via mythtv-setup and discovered that closed-captioning data still wasn't being captured or displayed, even after booting both the MBE and the SBE/FE. However, when I followed the (excellent! thank you, Hans!) directions in ivtv/README.vbi, and did "ivtvctl -b wss,cc -x 1" and "ivtvctl -w wss,cc" on the SBE/FE's 350, CC in LiveTV worked immediately. Similarly, doing the former command on one of the 250's in the MBE also gave me a recording w/CC data in it.
Is there some reason why, if someone sets the VBI/NTSC option in mythtv-setup, Myth doesn't automatically do this for all x50's it finds in all backends? It's counterintuitive that someone who wants CC data has to turn on this flag and it still does absolutely nothing unless they happen to have read a file in ivtv's source code tree. (Fortunately, I read that a while ago and remembered that it was there.) It also means I now need to decide how late in the boot process (and thus where) I should embed a script that iterates over all the video devices and sets this up; the right time would seem to be when a backend initializes itself instead. [In fact, now I'm wondering whether this UI flag does nothing at all, but I'll leave it alone instead of flipping it back and (maybe) rebooting just to see.] I don't see any evidence that this is different in SVN, but maybe I've just missed it somehow. (I'm not running it, but I searched the archives.) Thanks...
