[mythtv-users] cardinput.inputname = NULL

[Mike Robinson]

I've been running version 0.19.20051208-1 for about two weeks now.  I 
was able to watch live TV (to some degree) until yesterday and I'm not 
sure what changed it.  I have two HD-3000 tuners.

When I first set the system up, I could select "Watch TV" and start 
watching live TV as long as there wasn't a recording in progress (even 
if the second tuner was available).  It was annoying, but being an SVN 
version, I let it go.  I could, however, record two programs at once.

As of yesterday, nothing happens when I select "Watch TV."  I took a 
look at the backend log and noticed that it couldn't find the starting 
channel ("11_1" in this case).  I checked my channel settings in the 
database, and verified that it existed.  I then checked the database 
queries in the log, and noticed that it successfully tunes to the 
starting channel, at first.  Then a second query occurs, but specifies 
that the "cardinput.inputname" must be equal to "NULL" instead of 
"DVBInput."  This requirement causes the query to fail.

I can still record with both of the tuners.

Any ideas?

                         Most likely, your DefaultTVChannel setting is wrong
