"Broadband" also simply means not dialup. There are DSL connections that cannot sustain 1mbps, yet they are called broadband.

For the OP: for a tube you really should invest in a streaming server that can detect bandwidth, or use a player like Flowplayer that has a bandwidth plugin that works with progressive downloads. You don't have to actually provide a bunch of links. This is 2010, after all.

Many of the tubes I'm seeing have a 300kbps or so version for "guests" and reserve higher resolution and HD to paying members. Gives them a reason to upgrade.
