OK I guess I wasn't clear. I am not talking about encrypting the PAT/PMT. Considner this example.

TRANSPONDER 1 - PROGRAM 1 (FTA)
TRANSPONDER 2 - PROGRAM 2 (ENCRYPTED)

If you only wanted to deal with FTA channels you would have something in your dvb_channels that
was like this:

TRANSPONDER 1 FREQ,POLARITY,SYMBOLRATE,SID,ETC

So then if next week the TRANSPONDER setup was like this:

TRANSPONDER 1 - PROGRAM 1 (FTA)
TRANSPONDER 2 - PROGRAM 2 (FTA)

You then fire up the scanner built into myth and I have a broken provider that doesn't show the
existance of each transponder (Common in NA)..

I would select just TRANSPONDER 1 in my scan by going the distinct method you mentioned therefore
I would be unable to ever know of hte existance of PROGRAM 2 until I manually put it in.

Does that make sense?
