with the release of boxee for ATV 2.3, we have changed the way boxee interacts with the remote. under some cases, this causes users who are upgrading an existing boxee install to freeze at login.
to fix this, one needs to remove his/her configuration file. a new one would be generated which fixes this issue.
- please see this thread on how to connect to your ATV using ssh, by following steps 1 & 2
- at the prompt, doCode:rm /Users/frontrow/Library/Application\ Support/BOXEE/UserData/guisettings.xml
- start boxee and you should be good to go
