dvbscan only inserts 0 pid where it cannot find one. 0 is not what is broadcast 
but is inserted so tzap can recognize it and not tune it in. Myth on the other 
hand will try to tune into 0. (I dont even know if 0 is illegal value or not, 
maybe sometime some channel will actually broadcast on 0). It also only inserts 
the first video/audio pid it finds. Often channels have a few audio streams. I 
believe myth can accept multiple video/audio streams and will record them to 
disk. Swapping between streams on playback is more tricky.

Anyway. I just run this:

./dvbscan -5 dvb-t/uk-WinterHill |cat  ~/.tzap/channels.conf - \
	|grep -v :0:0:[0-9]*$|sort |uniq > ~/.tzap/channels.conf.new; \
	cp -f ~/.tzap/channels.conf.new ~/.tzap/channels.conf;

Which updates channels.conf file and gets rid of the 0,0 pid channels. You still 
have to eyeball it as it can go wrong. I found the other day that price-drp.tv 
is broadcast on two multiplexes while they do a switch over.

It caught the new channel (abc1) which I added to zap2myth the other day along 
with its icon. (Shame there is nothing on it to watch)
