2223,Muxing dvb_teletext in mpegts does not work,burek,,"Summary of the bug:
When ffmpeg is instructed to do ""-c copy"" on input stream, it unexpectedly converts one of the input streams of type dvb_teletext into dvb_subtitle. More info can be found here: 
http://ffmpeg.gusari.org/viewtopic.php?f=16&t=811&p=1527

How to reproduce:
The original scenario, where the possible bug was discovered, used a command line like this:
