ivtv: Toggle Teletext Captions does not work

Description
When assigning the Toggle Teletext Captions (TOGGLETTC) action for the 'T' key, the Mythtv OSD subtitle page (default 888) is not displayed. Enabling the teletext menu via the OSD menu and selecting page 888 manually is working, so it's not a teletext problem. I'm using the IVTV drivers and a PVR250 card.
The patch below is a first attempt to resolve this issue by doing :
- explicit check on the kTrackTypeTeletextCaptions type in tv_play.cpp
- assigning valid OSD message and teletext page selection in NuppelVideoPlayer?.cpp
For the latter, it looks like the fancy calls to track descriptions and language tracks are not fully functional and therefore resulting in wrong values (page = 0?) and skiping the Teletext OSD display routine.

Guess you mean it breaks the DVB Teletext captions. Is the OSD message and page indeed extracted from the DecoderBase::GetTrackDesc?() and DecoderBase::GetTrackLanguageIndex?() functions? It looks like these routines do not function for IVTV Teletext caption.

barnasc, Is this still a problem, and if so do you have a short sample of video displaying this problem?
"T"oggle teletext works with the limited set of samples that I have here.

No info provided. (Given the age of this ticket, not surprising). If anyone does have a sample that would be useful, the issue is probably that Martin is in some country that uses a different page for closed captions than any of the pages we look at for captions.
The patch does not look right, but keeping ticket open for problem description.
