Note that the youtube option is for the live concert only, while with the MLB package, you can re-play the shows for 30 days after the event (until August 7 I believe). So while you may not be able to watch the shows through your apple TV, you get way more bang for your buck with the MLB option.
I plan to plug my computer into my receiver and watch on TV that way.
I bought my pass when they first announced the stream, and I was able to save $50 off the "All 5" package. Since then, they have added lots of options. For those who have not purchased yet, I would stay away from youtube, since you only get to watch once. I believe the cable pay-per-views will also be available for 30 days after the shows, but those seem to be available for Chicago only. So I would suggest the MLB stream for Santa Clara, and pay-per-view for Chicago. The Chicago shows will also be broadcast on SiriusXM (not sure about Santa Clara), so the free 30-day trial they offer is recommended for those that won't be able to watch on TV. Hope everyone enjoys the shows.
