This command executed OK and produced a valid m3u8 URL for the 2565 video.
But for that I already had a working extraction command using curl.

Back to video source Id=2308
----------------------------
Yesterday evening I grabbed a new m3u8 URL using FireFox and then I set up a
number of at jobs to use that in order to download small 20 s snippets every 10
minutes for 3 hours overnight.
This was done to check for how long such an M3U8 would be valid. I expected 1-2
hours.

Surprise!
All of these small downloads completed and if I test now it still works!
So I have expanded that test with a new set of at jobs for a couple of hours.

It seems like I have found a "golden" URL by chance!

Previous testing showed that even a 2+ hour old URL from FireFox did not work
for the actual show download.

I hope this URL will stay operational for at least a day or so.

Could it be that it stays working as long as someone (me) keeps using it at
regular intervals?
Like some server side timeout?
If so I could just set my system up to download a bogus snippet every hour or so
to keep it living...
