I recently plugged an access point into my gigabit switch here at home
so I could use my new laptop around the house.  I found though that
watching dvbstreamed video didn't work properly any more.  Both the
computer which has the capture card in it and the computer on which I
wanted to watch the video are connected directly to the gigabit switch
(and have gigabit interfaces).  Just the addition of the AP to the
network caused the video to be choppy and unwatchable.

What is going on here?  The best I can guess is that since the packets
can't get out the AP's wireless interface fast enough it's actually
slowing down the sending rate of the video streaming server.  Shouldn't
my switch just drop the packets if the AP can't deal with them quickly
enough?  Or is it something to do with the higher level protocol (RTP)?
*confused*

I have a DPandA card, btw (a rebadged TechnoTrends card with no MPEG2
decoder onboard).
