I misunderstood that?
All PIDS in a single line just separated by ',' is not safe (teletext,
radio, ac3, etc...) without adding more codes to parse them. Much safer and
cleaner separate them by columns..., also easier to add new pids as long as
we support them... less parsing and no need to change current working
fields. Preserves compatibility. Better to do something like that now than
I've already spent some hours splitting them =)

If it's already stored, we will have faster channel switch. Once it's tuned,
certainly we can parse them to get updated information depending on the
program being broadcasted, user prefs etc, but that's not currently
developed yet, so we still need anyway.

from stune output
Usage: dvbtune [OPTIONS]
-f freq absolute Frequency (DVB-S in Hz or DVB-T in Hz)
or L-band Frequency (DVB-S in Hz or DVB-T in Hz)
-p [H,V] Polarity (DVB-S only)
-s N Symbol rate (DVB-S or DVB-C)
-v vpid Decode video PID (full cards only)
-a apid Decode audio PID (full cards only)
-t ttpid Decode teletext PID (full cards only)
-pnr N Tune to Program Number (aka service) N
-i Dump SI information as XML
program number = service (service is how is been known in vdr) anway they
I'll keep prognum to keep synched with Kenneth devs.
