Right, unless you specify a "LocalHostName" override (which we plan to 
change to a much better name--and, possibly, completely dissociate from 
host names), we use the host name, as returned by the hostname 
application (we use code similar to that used by it) as your default 
machine identifier.  Since all settings are keyed off of the machine 
identifier, you end up losing your settings and going with defaults.

That said, if someone can identify the setting that's causing the 
flickering, we can probably fix it--either fix the flickering or at 
least fix the defaults.  It's likely some setting in the playback 
profile group you get--though some have said that changing playback 
profile groups doesn't help...
