But you provided a different stream, didn't you?
How does the telxcc command line looks for the 
provided stream?
telxcc -i test.ts -o test.srt -t 43 -p 888 ?

Does it also work if you specify 8192?

I ask because I wonder how the teletext stream 
can be detected for the sample you uploaded:
The stream type is "0" which makes it difficult 
to detect it and I wonder if tvheadend does 
something "smart" - do you have another possibility 
to record? cat /dev/.../dvr or mplayer -dumpstream?

Thank you for the sample, Carl Eugen
