[linux-dvb] Crystal Palace - only some channels

Hi y'all.

I've finally got my Hauppauge WinTV-NovaT card working - through 2 inline 
signal boosters, but I'm not getting all the channels in my channels.conf 
file.

To test I'm simply using tzap in one window and piping the 
/dev/dvb/adapter0/dvr to mplayer


Can anyone explain why some channels in a multiplex work while others don't? 
For instance :

#Multiplex B BBC - Channel 28, Offset -, Frequency 529833333
#Community                (0x4e00) 01: PCR 0x1fff
#703                      (0x4c80) 01: PCR 0x1fff

I can get 701, 702, BBC FOUR, but not all the rest.

Also, it doesn't seem to be a factor of signal strength, snr etc as to which 
channels mplayer will display.  for instance :  looking at the below, I can 
watch 'Sky Travel' but not 'CHANNEL4' or 'ITV 1'

any ideas?
