Hello Gerry,
After a bit of guessing how the Fox news file format works with date and time I gave it a go on my test system and it works OK for me.
I just dropped a "Remote URL" into the live schedule and set it like the picture below.
I took that screen shot while the first attempt was playing and I was going to drop a second play further down the schedule.
It's a bit of a shame they don't have a constant file name for the newest bulletin (perhaps as an alternative).
Note that I'm in the UK and currently on G.M.T. so I had to find a file name that was available. This is the first guess that worked but might not be the newest for a bit after noon in the UK.
