The broadcast team can definitely make quite a different to the enjoyment.
If you are "downloading" the races maybe try the BBC broadcast.
I watch races on the BBC and the current lot are really excellent.
Along with lead commentator Ben Edwards we have David Coulthard and ex F1 designer Gary Anderson.
Can you get live timing in the USA? from say

Following the lap and split times can really add interest when the race is a little dull.
