Hi!
I have had a problem watching the teletext on the crypted channels "ORF1 HD" and "ORF2 HD" ... after doing some research on the web, i found out that these two channels not only crypt their audio and video streams, but also the teletext. (as far as I know, not even Sky/Premiere crypt their teletext)
So I had a look into the vdr code, and found out, that in ci.c in the function AddChannels(), only video and audio pids are added to the cam device.
I made a small patch (which is included in this mail), which also adds the teletext pid in case there was a tpid detected before, and now I can watch the teletext in the ORF HD channels.
Other channels, which do only crypt audio+video, but not the teletext, should not be affected by this patch, because the CAM module should be intelligent enough to detect whether a ts packet is crypted or not (via the two scrambling control bits in the ts packet header)
I wanted to ask, if it would be possible and reasonable to add this patch to the vanilla-vdr.
Kind regards, Michael Kaplan
