Sounds suspiciously like a DNS problem (the long delays).
Standard troubleshooting woulkd include resolving the various
hostnames using the "host" command, dig, and ping.  It should
only consume a few minutes to check.

While you're at the network layer, capture a network trace using
e.g. wireshark. Consult the menu item Analyze->Expert Info,
anything in yellow or red could be of interest. Under the
View->Time Display Format menu item choose "display offset from
previously captured packet". Any large unexpected delays would be
red flags.

Windows IPv6 networking is *ahem* crap. If you're interested,
try starting out with http://packetpushers.net/show-43-microsoft-teredo-is-crap/
or for the gory details http://www.potaroo.net/ispcol/2011-04/teredo.html
or Google for Teredo (Microsoft's IPv6 stack implmentation).

But you raise an interesting point. Could an IPv4/IPv6
interaction be causing mischief? Try disabling IPv6 (Google for
it) and see if that affects the issue. I do not suggest that you
permanently disable IPv6.

Earlier in the thread someone made a comment about power desktop
users.  AFAIKT, the real power users - I'm not claiming to be
one of them - customize fwvm and have it jump through every hoop
they care to think of. That takes pressure off the Gnome / KDE /
whatever ecosystem. Maybe that lack of pressure has harmed
things. Anyway, if you're attempting to play mp3's and 4's, does
mplayer do the job?
