[mythtv-users] Dual NTSC and ATSC setup

Thank you for getting back to me.  I understand what you wrote but I
have a couple of questions:

On the 1st setup section of MythTV you have to pick NTSC or ATSC.  After
you pick one of these for the first card, you can change it the second
time through for the second (or third etc) card but doesn't that foul up
the setting for the 1st card?

Putting two cards in a machine means that the "configure" file probably
needs to be editted to support more than one card type - such as IVTV
and DVB-T.  Yes / No ?  Or have you found one card that will tune from

Is there anything I have missed?

Thank you in advance
