To answer your question on EPG, no you do not need another tuner profile, but you need another EPG mode.
To set it up, just go to Tools > Options > Television, and click "Load Program Guide...". On the dialog window you should see two listed. Click Add button to add another one. This one is not directly associated with any tuner profile, but will work just the same. Make sure the checkbox in front of each item that you want to use are checked.
