That works for me. The direct analogy is:

    gst-launch-1.0 playbin "uri=BBC%20NEWS%20HD"

I put the output of running this at the end of the email. Running:

    gst-launch-1.0 playbin "uri=BBC%20NEWS"

the SD version of the channel works fine.

OK, I am probably missing something, but my assumption had been that
the parameters delivered by the real channel scan should deliver all
the parameters needed for the virtual channels and store them in the
virtual channels file.

The output for the pipeline above was:
