I also went through the test with test_ioctl, and sure enough it is Composite4.  Once myth was set to that - it worked!  Thank you for your help on that.  I guess I just had too many iterations of trying to config everything.

The setup displays a blurb about Myth using the first argument for the channel number, so I assume I should add the '$1'.  And then set the program to run in the background with the '&'.

But when I'm in MythTV, I still cannot use the remote control to change the channels.  The remote I'm using is the gray one that came with the Hauppauge PVR-250 card.  I either hit Channel Up or Down, or manually type in the channel.  I get a brief display of the time on the screen, then that fades away with no channel changing.

Prior to Anduins patch for tinny audio I was working around it with a perl script
to change channels + set the ioctls to avoid it. I am almost 100% certain I
simply had the binary name - i.e. the doc means myth will supply the channel
as the first argument on the command line.

Try just putting /usr/local/bin/channel in, with nothing else.
