[mythtv-users] PCTV nanoStick T2 290e dvb-scan

[Robert Logan]

Excellent hint there. I checked the tables in mythconverg and voila! A 
'select frequency from dtv_multiplex' showed a frequency I wasnt trying 
and the associated settings I used for CrystalPalace produced the result 
I was looking for:

So in uk-CrystaPalace, I added:
T 554000000 8MHz 2/3 AUTO QAM256 AUTO 1/32 AUTO

Now a './scan  -a2 dvb-t/uk-CrystalPalace' produces:
initial transponder 554000000 0 2 9 5 2 0 4
 >>> tune to: 
554000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_AUTO:QAM_256:TRANSMISSION_MODE_AUTO:GUARD_INTERVAL_1_32:HIERARCHY_AUTO
0x0000 0x4440: pmt_pid 0x0064 BBC -- BBC HD (running)
0x0000 0x44c4: pmt_pid 0x00c8 ITV -- ITV1 HD (running)
0x0000 0x4500: pmt_pid 0x012c CHANNEL FOUR -- Channel 4 HD (running)
0x0000 0x4484: pmt_pid 0x19c8 BBC -- BBC One HD (running)
Network Name 'London.'

...
with the normal dvb channels as well.

Many thanks for the thoughts.
