It's not supposed to, when there is a new channel you need to scan
for it using the channel scanner. Then the next time mythfilldatabase
is run it will add it to your zap2it listings.

In order to run --do-channel-updates on just one source you need to add
--sourceid followed by the source you wish to update.

As for why it is removing 4DTV channels... Are you tuning these directly
using a DVB-S card, or are you using some kind of box and recording the
analog output? If the former, just scan each transport in the channel
scanner to get all the tuning data. If the latter, make sure this lineup
is only connected to the analog capture input.
