FS1 worked just fine this week, I had to sign up for a 7 day trial on Playstation Vue to watch s a few things including the 500 on Sunday which I will have to remember to cancel by next Saturday so I don't get charges, but for the rest of the season, I will be using FS1 and NBCSN for watching races.
That said, I wonder how long this format is going to last, the owners are going to get mad if their equipment gets torn up every single week, I will be interested in seeing what happens on Sunday, because Friday and Saturday have been very expensive!
