[mythtv-users] need query to remove DVB transports

[joe byrne]

How do I remove DVB transports?  In an effort to get my air2pc (atsc
dvb) card working, I attempted to follow the directions posted at
http://www.digitalregime.com/mythdvb/setup/. Unfortunately step 4A is
out of date and I ended up adding a bunch of bogus transports.  How
can I delete them?  I've changed them all to be at 0Hz, so a WHERE
clause should be easy to formulate.  I just don't know which table(s)
I need to hack on.
