I will pipe up again here, that avahi would be nice
🙂I would suggest booting a LIVE CD and doing ZERO configuration to it. Open a terminal window and make sure that DNS is working as you expect. Maybe the domain name needs tuned?
There is an "option ndots:2" (approximately) that we had to add to our resolv.conf for a while because the system resolver would not automatically append the "domainname" if there was more than one DOT in the name. We have a corporation that has names like host.sub.domain.com, and people tend to like to use "host.sub" and assume the "domain.com" will automatically append like it does in Solaris. I don't know if this is the case for your configuration, but I suggest putting:
http://HOSTNAME.home./path/to/file.mp4(i.e. the trailing dot tells the resolver that its a FQDN)
