Did you actually check to see what Channel Group was active in the 
guide?  Use the MENU to verify it's showing "All channels".

It's much easier to just add a <LocalHostName> override in the 
config.xml file, which will tell MythTV to use the specified name 
instead of the host name to identify the configuration for the system.  
If the specified name is one that has never been used with MythTV, you 
will get all-default configuration.

Though even better would be to actually post a log file (at default 
verbosity with /absolutely/ nothing cut out) showing mythfrontend 
startup and then going immediately into the guide.  Then we could likely 
see what error is causing an empty guide rather than just guessing.
