[mythtv-users] Is the channelscanner working (DVBS/DVBS2)?

I'm running svn 21328, and I'm wondering if the channelscanner is supposed
to work. I can scan fine if I enter the tuning parameters in the dialog for
a single transponder. However, What I really want to do is to fill my
dtv_multiplex "from scratch", either by importing a channels.conf file,  or
filling the table from the NIT. Attempting to import the channels.conf, I
get a popup saying "Programmer Error, Incorrect Card Type"; clicking on OK
then pops up "Programmer Error, Failed to Handle Tune Complete" and then the
scan progress stays at 0% "forever.

Debugging with -v channelscan,channel shows this when attempting to import:

In addition, the channel scanner, even when scanning individual
transponders, never seems to fill dtv_multiplex from the NIT (scanning 19E
service info transponder on 12551500, and other transponders) never fills
dtv_multiplex with additional  transports.

Is this a bug ? This doesn't look to me like the bug reported in #6697.

I'd really like to avoid entering all of the transponders by hand......
