MANY MANY thanks patrick!
I ran the Zap2itPlugin.v1.6-Post10456-SVN-BIN.zip file you provided against the latest SVN (Rev 10586) and it worked perfectly from what I can tell.
I started with NO TV Channels and now the TVDatabaseV21.db3 file is now 27.2 MB and fully populated with my zap2it account channels.
The entire process took about 20 minutes from first starting MediaPortal.
I did have to go into Televsion -> TV Channels-> TV Cards: and map each available TV Channel to the correct TV Card.
I also had to go into Television->TV Channels
and edit the ATSC channels just as you described in the above posts.
I also had to Autotune my ATSC channels but this was to be expected.
Thanks again!
Glad it seems to be working ok.
I posted in the developer forum and put a patch on SF about
the ATSC channel edits, so maybe one of the MP devs will look at it.
