In case it wasn't clear, you should only expect "live" TV and new recordings (after you make this change) to have CC data.
A good way to test this is to use "ivtvctl -K 1" to turn on passthrough mode. If you still don't see captions using your TV's CC support, experiment with the commands you added to rc.local. Let me know if this helps. My household also depends on CC, so provided there's no hardware issues, I am confident we can get this working for you. (I have a PVR-350 and a PVR-150 and CC is working acceptably with both cards.) --scott On May 4, 2007, at 6:09 PM, Adrian de los Santos wrote: > Im using NTSC, thanks for your suggestions. > > I add > > /usr/local/bin/v4l2-ctl --set-fmt-sliced-vbi=cc -c stream_vbi_format=1 > /usr/local/bin/v4l2-ctl --set-fmt-sliced-vbi-out=cc > /usr/local/bin/ivtvctl -w cc > > to my /etc/rc.local but i still dont see captions using the tv cc > support or in mythtv pressing "t" (i get the "NO CAPTIONS" message). > > Any other thing that i can try ? > > thanks a lot. > > > > On May 4, 2007, at 4:01 PM, Scott Reynolds wrote: > >> You didn't mention if you are using NTSC or PAL.
