Guide data...where does it come from?

[jump]

I have one question...

How does the Guide Data get downloaded? Is it across the spot beam or over the phone/broadband connection?

I thought it came across on the spot beam, but a friend says it comes across on the phone line, that is why the box dials up every day.

Any thoughts?

DirecTivos come from the sat, Standalone comes from the phone.

Both dial up to verify Tivo subscription info, but the standalone downloads guide data, and the DirecTivo uploads PPV purchase info.
