I have run two streams of MythTV over a single 802.11b network without
any problems. I'm using 640x480 2200kbit MPEG4, with default quality MP3
audio. I ran iptraf on my router and it was pushing about 5Mbit, and
receiving around 400kbit. Still well below 11Mbit used. My machines at
the time were about 80 and 90 feet away from the AP, both with around a
75% signal quality and an 11mbit link.

Maybe you are using higher bitrates? Unless I'm missing something, when
you're talking about network usage, bitrate is far more important than
resolution.
