Comment (by pbennett):

 Setup - With latest master (Pre-30), and on v29, the import recorder setup
 takes you to a file browser to select the import file. You cannot select a
 file that does not exist. You can type in a file name that does not exist
 and as soon as you move out of the input field, the file name you typed is
 cleared out and replaced by "/". However, that is all good, because with
 the file name as "/" it is a file that does not exist and it works as

 I created by own shell script to record from DVB using zap as you
 suggested. Without your patch, the recording never gets going. With your
 patch it is recording successfully, just like a normal input card.
 Attached is my script that has to be used in the recording started event.

 I found that using the recording ended event does not work. I had hoped to
 use a script there to end the recording when MythTV decided the recording
 was ended. However MythTV did not sent the end recording event until I
 first killed the ffmpeg, even if it was several minutes past the recording
 end time. So I switched to timing and killing the recording from inside
 the start recording event and adding "&" to the start recording event
 invocation so that it continues running through the entire recording.

 I did not fully understand your python script. Do you have a check in
 there for the card id? I added that in my script because you do not want
 the import to start up when recording from other types of cards on the
 system, for example I have a ceton tuner as well, which is recorded in the
 normal way.

 Live TV is a problem. It starts recording perfectly on the backend, but
 the frontend freezes forever. I would like to have that working as well.
 It should work, Live TV is perfectly capable of handling tuners that are
 slow to tune. It may be that the frontend expects always to find some data
 in the file, if you tune a channel you normally immediately get a file of
 some 500 bytes, not 0 bytes as we see when starting with import recorder.
 Note Live TV does work with import recorder if you just use a file copy in
 the import script so that the file is there by the time the frontend looks
 for it.
