9669	External Channel Change Event Doesn't Fire for DEMO/MPEGTS Tuner.	raymondboettcher@…	danielk	"I have a small problem and can't determine if this is just a problem with my MythTV installation or the event wasn't configured for the DEMO Tuner.  I created 3 DEMO Tuners and allocated them to different FIFO's in the /tmp folder.  I have 3 FFMPEG instances set to stream to those FIFO's as they are called upon.  I'm writing an intermetiate program that will pass the data from the specific feed to the FIFO Device.  However, when I change channels it doesn't call the external channel change event.  When I have several DEMO Channels setup to one lineup it keeps the existing Tuner (which is fine) and shows the same feed regardless of channel tuned too.  I understand that the driver is VERY simple and this normally would be the desired output.  However, with the External Channel Change Command, I could modify this behavior.

I would assume that the channel changing event is part of the Myth Code itself and not the responsability of the tuner driver in MythTV.  I can run mythbackend -v channel to see the channel change taking place.  However, I'm still studying to code to get a better understand of what is going on.

I'm running the latested Development code (pre-0.25) because of some problems with 0.24 when handling Live TV on Slackware-64.  This update fixed the Buffering timeout problem when accessing a Live TV or Prerecorded Feed.

I also get a few ""LoadFromScheduler(): Error, called from backend."" when changing channels and wasn't sure how to go about displaying the information of those errors in order to determine if that is the attempt to run the script.  I ran it from a shell and it did exactly what I expected.  I even wrote a small C++ program for it to run simply to dump the arguements passed by MythTV into a file in /tmp."
