But the OP's talking about online video streaming, where the first bottleneck is his Internet service and associated hardware. Hulu technically works over 3 Mb/s Internet service (or even lower), so in theory wireless-b has enough bandwidth. But wireless performance varies with distance, obstructions, interference, and crowding, so it's never easy to say how well it'll actually perform. This is why wired is pretty much always better, except for the wires.
OP, it's hard to say. But if you want a reason to upgrade, here's one maybe: 802.11b generally has poor security. WEP was broken long ago, and WPA2 is the in thing.
Edit: On second thought, it really doesn't look like a simple bandwidth issue. If you had a bandwidth problem, you'd know that by long "buffing" pauses, etc. -- occasional hiccups would be caused by other factors, and not necessarily go away with a bandwidth/wireless upgrade. Motion problems however could be an issue with the nature of the original signal and attempts to reduce the Internet bandwidth requirements.
