something to remember though, is that there is ~5Mb overhead with an 
802.11 connection.  so, even though you were only pushing through 5Mb, 
you were pretty much at the limit there.

personally, i just ran a cable for the time being.  when the G stuff 
starts selling for prices similar to the B stuff, i'll upgrade my router 
and buy G cards for anything new, including the mythtv box.
