OK, thanks to Jon's helpful pointers I can now run tzap!  Can someone please
confirm that these ber numbers are way too high for decent reception.
However, there is one slight gremlin here, BBC ONE which has the lower error
rate won't play at all nicely through mplayer, however, ITV 1 which has
substantially higher error rates plays "OK".  (OK means that the picture and
sound both look fine, but to my ear there are slight hiccups in the sound
which might be because of unfixed errors in the audio stream?)

So this one plays really poorly

mm dvbstream # tzap -r "BBC ONE"
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 505833330 Hz
status 01 | signal c5c5 | snr a1a1 | ber 0001fffe | unc 00000000 |
status 1f | signal c6c6 | snr fefe | ber 0000009a | unc 00000000 |
FE_HAS_LOCK
status 1f | signal c6c6 | snr fefe | ber 000000bc | unc 00000000 |
FE_HAS_LOCK
status 1f | signal c5c5 | snr fefe | ber 000000be | unc 00000000 |
FE_HAS_LOCK
status 1f | signal c6c6 | snr fefe | ber 000000ae | unc 00000000 |
FE_HAS_LOCK
status 1f | signal c5c5 | snr fefe | ber 00000078 | unc 00000000 |
FE_HAS_LOCK


However, this one plays "fine":

mm dvbstream # tzap -r "ITV 1"
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 481833330 Hz
status 00 | signal c7c7 | snr 4343 | ber 0001fffe | unc 00000000 |
status 1f | signal c7c7 | snr fefe | ber 00000174 | unc 00000000 |
FE_HAS_LOCK
status 1f | signal c7c7 | snr fefe | ber 0000013c | unc 00000000 |
FE_HAS_LOCK
status 1f | signal c7c7 | snr fefe | ber 000001a2 | unc 00000000 |
FE_HAS_LOCK
status 1f | signal c7c7 | snr fefe | ber 000001a0 | unc 00000000 |
FE_HAS_LOCK

I think that there are other problems here though, because my full featured
card has ber numbers of "0" (or occasionally "1")

Please, any thoughts really appreciated!
