Which articles were these? I'd be really interested in seeing if I can track down a changelog of some kind.
@Goat: I did it using the standard YouTube Premium App. Worked fine; half the time I suspect the video had the proper tag in it and so the TV automatically activated 3D mode, and in the case of the side-by-side or top-and-bottom ones, you just hit the 3D button and picked what type it was.
What concerns me a little is that they have been advertising the addition of NHL GameCenter access to the Premium Apps somewhere in the June timeframe, and it's still nowhere to be seen. Yes, the season is almost over and GameCenter LIVE is effectively done, but there is still the archives and the Vault, and I'd like to see how well it works and see if it will be a viable option for watching games next season. (This season I did it on a Roku, and the NHL implementation on Roku blows goats. (No offense, Goat.

)
(And I know it's not June yet, but it's close, and if they just shipped an update, it seems reasonable not to expect another one for a couple months.)
