Unfortunately, the lack of a ground connection to a laptop power

But as you're lucky enough to have a setup that works well, you need
worry about none of this! :-)

I must just be lucky then!

About the only problem I find is that the screen saver kicks in on
streaming videos. (This is probably not a problem for most pop videos
- but classical operas usually last for more than three minutes. :^)

Slightly off topic, the Franco-German channel Arte is starting to put
complete classical concerts and operas on line at
http://liveweb.arte.tv/. This has not been going long, but is starting
to look promising.
