HomePlug 1.0 [14 or 85Mbit/sec] doesn't seem to have any quality of
service mechanisms but HomePlug AV [200Mbit/sec] does, indeed that's why
it has the "AV" tag. I've never quite found out how to explicitly
activate the mechanisms in HomePlug AV though. According to the specs
it's capable of 4 types of Quality of Service: Guaranteed bandwidth,
quasi-error-free service, fixed latency and jitter control. My
experience is the HomePlug AV is perfect at streaming between my MythTV
frontend and backend and I don't think that's just down to the extra
bandwidth.
