There is a delay as far as the buffering is concerned. Between 70-110 seconds. Meaning a little over a minute to almost 2 minutes in delay.
Depending on where you live(your ZIP CODE/Address comes into play here) will determine "LIVE" games from teams that will be blacked out. For myself, as an example, I am blacked out of "LIVE" games for both the Pittsburgh Pirates and the Cleveland Indians.
All other games(unless they are being NATIONALY BROADCAST on either ESPN or TBS on Sunday Night or Saturday respectively) are broadcast LIVE.
So if you are a SF Giant fan, and your game is on at 10:05 EST and the game is not on nationaly(it may be being shown on ESPN, but it is not considered a nationaly televised game, as they may be showing other markets other West Coast games), then you can watch it "LIVE" via the ROKU player.
I decided not to get it this year because between ESPN, Local teams(Pirates and Indians), FOX on Saturdays, and TBS on Sundays, and now MLB Network(I have Time Warner Cable), it is really kind of a waste of money IMHO.
Especially if they do not improve the picture from last year. Granted it was a BETA version, but they really need to improve the picture, based on bandwidth. VERY BLOCKY and not all that great.
