I feel really bad for asking this, as I'm sure it's been answered, but I'm not sure how I would add a new skin to my Apple TV. I imagine it has something to do w/ SSH (which I know next to nothing about).
If someone could help me out or at least push me in the right direction I would appreciate it.
Install new skin
1) sftp (ssh file transfer protocol) into apple tv.
server/host=ip port=22
user=frontrow password=frontrow
apps
windows-filezilla
OSX - cyberduck
2) browse to "/Applications/XBMC.app/Contents/Resources/XBMC/skin"
you may need to browse back a few times to get into the root dir
3) just drop them there and restart XBMC if it was running
4) in XBMC goto system->settings->appearance to change skins
Change RSS feeds
"RssFeeds.xml" is located at "/Applications/XBMC.app/Contents/Resources/XBMC/userdata"
Copy to your computer. Edit it and save to back to the apple tv. (make sure to override the old file)
