Hi Roger....
Thanks for the replay. Actually the MythTV feature of MVPMC behavior I
see is more complicated than that. If I use the normal Live TV option
the MVPMC box sees 2 tuners (good) and list both the normal and high
definition tuners. But when I try to tune in what appears to be a
standard definition station, the MPVMC box resets. However, if I try
the New Live TV, it goes directly to a standard definition station and
plays great. Except when the tuner is in use. It doesn't look like New
Live TV handles this well. Maybe we need to check and print out a
message if the tuner is busy.
Viewing lists of recorded shows gets a bit tricky. I usually get the
"MythTV connection lost!". I immediately tested the back end by running
the front end and playing several of the pre-recorded shows. It worked
fine.
In general, the current state of the MVPMC / MythTV feature appears
delicate to me. As more thing worked before I reconfigured my Mythtv
box to have 2 tuners, I believe it's more to do with unexpected modes of
a 2 tuner back end than MVPMC. I recall both the older Live TV and the
Watch Recordings working before. However, as I resynchronize with GIT
often it's hard to narrow down when they stopped working to any one event.
It might be important to note that the duel tuners used above proved
difficult to integrate into one MythTV box as one is normal and the
other is high definition. I had to use two different zap2it lineups as I
did not intend them to receive any common stations. A normal front end
makes you choose which tuner is to be used for live TV watching. Perhaps
this might be a reason the older Live TV / MVPMC feature resets (I am
guessing the older Live TV feature assumes two identical tuners with the
same lineup).
I recorded the output of the MVPMC box and of the back end when trying
to list the recorded shows ("Watch Recordings"). First the MVPMC box
then the MythTV backend:
----------
show busy widget
get recorded failed
mythtv_shutdown(): closing mythtv connection
Event socket closed, shutting down myth
mythtv_shutdown(): closing mythtv connection
MythTV connection lost!
MythTV connection lost!
hide busy widget

Let me know if there or other outputs and / or events which you might
want to see.
...thanks
