Thanks Tim, but unfortunately I don't have VLC loaded (I'll look into it)
.
I have a little scriptlet that takes an executable name and
extracts urls from piped-in whatever and gives me a choice
which url to be returned to call the executable with, so I tried wget to
see if I could see what the .mpd was:

I have not yet configured dnsmasq -- do you think the above is a DNSSEC problem
that would be solved by dnsmasq? (does someone have a QND quick-and-dirty how-to
for configuring dnsmasq, spelling out any gotchas -- or should RTFM suffice?)
Or do you think ccwebcast.in2p3.fr might have the same/similar subdomain issues
as savannah?
I can ping both domain and subdomain though:

... so idk -- maybe I can bypass DNSSEC problemss with /etc/hosts ...
Will try that, just to add a data point :)
Nope, doesn't seem to change anything ;-/
