[linux-dvb] inital tuning data for dvb-t in nuernberg

minor fixes/additions:

the vhf transponder on t184.5 mhz is 3/4 fec, not 2/3 like every uhf
transponder
and strangely but true:
here seems some dvb-h test going on which is in reality just dvb-t with
other parameters
on the 30th i noticed the following transponder on channel 50 which i
cannot find in any listing, nor any information about it. but its there
and can be revieved in the north of nuernberg and south of erlangen.
at the moment i can only guess its transmitted in tennenlohe.
its pretty weak in power. polarisation seems to be vertical
it is a test from the fraunhofer iis and the LIKE (professorship for
information technologies, section communication electronics)
video shows pong played by a computer. the audio seems to be the same
as on drm (digital radio mondiale) 'bit eXpress campusradio' on
15,896 MHz

so add it to the initial tuning data if you think it does not hurt.
T 706000000 8MHz 3/4 NONE QPSK 2k 1/8 NONE     # frauenhofer dvb-h test

one strange thing i cannot find the reason of is: if i scan using this
data with kaffeine everything is fine.
if i scan with 'scan' it finds every transponder, but keeps looping a
_very_ long time and tries to scan 212.5MHz and 690MHz which are
carriers in Muenchen, but i checked and they are shurely not recievable
here. the information seems to come from the NIT, and is used, even if
i omit the option -n
also i get a lot of dups and some channels are duped but differ in the
fec-lo setting (most use 1/2 and some the same as fec-hi)
should the fec-lo be left on NONE (seems its done that way on nearly
ever initial tuning data)
