[mythtv-users] Can't use MacOS X frontend on wireless network

Same problem here.  I think it has more to do with OSX + MythTV than the 
network, but I have no idea how to fix it.  That being said, I've found 
that disabling other network programs (ssh, fire, web browser, etc.) 
helps considerably. 

Also, on my iBook (1.2ghz + 1g RAM), MythTV runs 60%+ and spikes much 
higher.  Firefox sucks up a lot of CPU, so I have an especially hard 
time watching TV and browsing concurrently.  In my experience, the OSX 
sheduler isn't even in the same league as the one my Linux box.  When I 
have all the various processes reniced to give MythTV the highest 
priority, it still stutters when I do something else.  Compare that to 
my Linux box which I can be doing 10 things at once and it NEVER skips.

MythTV on Linux is bleeding edge.  MythTV on OSX is bleeding edge of a 
bleeding edge.  I expect it to improve over time. ;)
