I mean using teletext PID in VDR and reading it via TV set.

I've seen that by checking the code.
Now, with ttxtsubs plugin installed and loaded, this is the observed 
behaviour:

As an example, Taquilla 2 has TPID 62 (got it from ProgDVB). Once 
removed TPID from channels.conf (to avoid a possible conflict between 
VDR and ttxtsubs plugin) and tuning to that channel, this is what's 
printed on stdout:
ttxtsubs: Found non HI subtitles on PID 62, page 888
but, if I retune that channel...:
ttxtsubs: Found non HI subtitles on PID 53, page 888
and that "PID 53" (TPID for Taquilla 4, same transponder) can turn 
into "PID 50" (TPID for Taquilla 15) if I restart VDR, etc.
Also, sometimes, stdout (stderr) message is:
ttxtsubs: Subtitles for language "spa" not found on channel, available 
languages: esl
Ttxtsubs, as it can't find such a "esl" language, it just displays 
nothing on TV. "esl" doesn't appear on ttxtsubs.c.
Isn't it all weird?

That can be a starting point to debug, thanks. I'll keep you updated 
about my findings on this.

I'll get that one too.

Cheers!
