>I am very new to this list, so please excuse my ignorance as to the
proper approach. I posted this on the user group but got no response, so
I thought maybe it was better to post it here. I have a PCHDTV 5500 card
running Suse 10.1, Myth 0.20-12. The DVB side works fine. The S-video is
connected to the output of my Satellite receiver. I am having a problem
scheduling a recording on the S-video. I can watch Live TV on the
Satellite and can even do a manual record, but trying to schedule a
recording fails. In the backend, if I leave the “External channel change
command” for the S-video input blank, I get an error when the scheduler
tries to “change channel” which causes the recorder to fail. Note that
the channel “Frequency” for there channels is set to NULL

until the scheduler tries to record something via the s-video. As you see

Never tried gdb before, When I attached the file, it was too large, so I
have copied what I hope are the important lines here. I can mail the file
