[mythtv] SchedulesDirect, multiple lineups -- second lineup is empty

[Sean Cier]

I just upgraded to 20.2 and switched to SchedulesDirect.  I have two 
lineups configured in SD (same account, same provider, just Cable and 
CableDigital).  Two sources (a PVR-500) are connected to the Analog 
lineup, and my Firewire STB is connected to the Digital lineup.  Problem 
is, while the channels and listings seem to be updated beautifully for 
the Analog sources, the Digital input gets nada: no listings, no 
channels.  I tried deleting all my sources and all my cards in 
mythtvsetup and recreating them, with no change.  Even hitting the 
"Fetch channels from listings source" (for my firewire input in under 
Inputs in mythtvsetup) does nothing: "Starting channel" remains "Please 
add channels to this source" (unlike the analog lineup, which works fine 
and lets me select a starting channel).

What am I doing wrong here?  Where else should I look to fix or even 
just diagnose this?
