Oops, there was an error there, I was supposed to enclose the channel  
name in quotes, so it simply used the wrong frequency. Still doesn't  
lock though.

[root at htpc szap]# ./tzap -c channels.conf-dvbt-crystal-palace "BBC ONE"
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 505833333 Hz
video pid 0x0258, audio pid 0x0259
status 01 | signal 7cb8 | snr 0000 | ber 001fffff | unc 00000000 |
status 01 | signal 7cd9 | snr 0000 | ber 001fffff | unc 00000000 |
status 01 | signal 7cc7 | snr 0000 | ber 001fffff | unc 00000000 |
status 01 | signal 7cdd | snr 0000 | ber 001fffff | unc 00000000 |
