OK, that wouldn't be a problem (I think) since I have a little table in 
my specs containing so-called «services». I'll just write down what is 
in the specs, and thus giving the info André has requested:

<specs>

RF-Channel: 43 (F_DVB-T = 650 ± 4 MHz)

Technical data of the OFDM-Signal
=================================
- FFT-Mode: 8k
- Constellation: 16 QAM
- Code rate: 2/3
- Guard interval: 1/8

Technical data of the Statistical Multiplex
===========================================
Transport Stream ID: 8000
Network ID:          16978
Network Name:        Pilot Mue

and then a table whose columns are named like this:

  ID    Name      PMT-PID   PCR-PID   V-PID    A-PID
-----------------------------------------------------
  900   Sv900     300       301       301      302
28107	BFS       100       101       101      102  *
28901   BR-Alpha  200       201       201      202  *
50001   Sv50001   400       401       401      402

</specs>

Using a TV I've found out that the V- and A-PIDS marked with an * are TV 
channels. There is also a radio channel with VPID 0 and APID 3001. I 
suppose that the Sv* ones must be the data PIDS.

Thank you very much for your time!
David.

P.S.: I'm doing the probes in Munich, where DVB-T is being tested (in 
2004 it'll be officialy enabled). Actually there are two TV channels and 
a radio one, plus a test network stream.
