MV doesn't really inject noise so much as supress the video sync pulse. VCRs and DVDRs are made deliberately so that they don't pick up a weak sync pulse when recording. I think the DVDRs will outright refuse to record such a signal. They'll digest a weak sync pulse just fine during playback, however.
Just think! DC Power Bus... Standard connectors... Good-bye wall-warts.... Mmmmmmmm... Donuts!

Maybe a world-wide mesh would best be implemented by licensed volunteers, like the ham radio model, but without the FCC. Maybe the EFF instead. :)
But they *will* be selling it soon....
