Devices that let you watch Netflix and other streaming video services on a big TV screen are popular, but there are limits to what you can watch.

NBC, for instance, didn't make its Olympics apps compatible with Roku, Apple TV and Google's Chromecast. With HBO Go, Comcast subscribers can use Apple TV but not Roku, while it's the other way around for Charter's customers. And with all of these devices, you need an $8-a-month Hulu subscription to watch what you can get for free using desktop computers.

Lionel Messi and Dani Alves scored second-half goals as Barcelona beat 10-man Manchester City 2-1 on Wednesday to reach the Champions League quarterfinals for the seventh straight season.

Barcelona advanced with a 4-1 victory on aggregate over two legs in which referees decisions — and non-decisions — played a big part.

Kobe Bryant won't be back on the court for the Lakers this season.

Bryant expressed only mild frustration Wednesday after the long-expected decision to end his 18th NBA season after just six games. The superstar guard's broken bone in his left knee has kept him out since shortly before Christmas, and it still hasn't healed enough for weight-bearing exercise.

Novak Djokovic rallied to beat Marin Cilic 1-6, 6-2, 6-3 in the fourth round of the BNP Paribas Open on Wednesday, avoiding the upsets that knocked out two other top-10 players.

Djokovic didn't face a break point on his serve after the first set in the baseline slug-fest that ended after midnight. He advanced to the quarterfinals against Julien Benneteau, a 6-3, 7-6 (4) winner over Feliciano Lopez.

Sebastian Vettel has a warning for those already writing off his chances of a fifth-consecutive Formula One title — the season is long and the team's current engine problems won't last.

The Red Bull driver has experienced a troubled off-season, with the team severely restricted in its testing because engine supplier Renault suffered a myriad of problems trying to make the sport's new six-cylinder turbo hybrid power-train function in anything approaching a reliable fashion.

Paul Pierce scored 17 of his 29 points in the third quarter and Mirza Teletovic scored 17 off the bench as the Brooklyn Nets beat Miami for the third time in as many tries this season, topping the Heat 96-95 Wednesday.

Shaun Livingston scored 13 points, Andray Blatche added 11 and Deron Williams had eight assists for the Nets, who've won seven of their past eight games and are 23-9 since January 1.

Since being cast in the film adaptation of "Fifty Shades of Grey," Jamie Dornan, who plays the S&M-loving billionaire Christian Grey, has largely stayed out of the public eye.

Aside from being spotted on the streets of Vancouver, British Columbia, while filming the movie, the 31-year-old Dornan hasn't walked any red carpets or really talked about the role.

Rob Thomas knew he might make movie history by using Kickstarter to crowd-fund his "Veronica Mars" film. But he wasn't prepared for the posters.

Of all the prizes offered to donors of "Veronica Mars" — everything from a digital copy of the script for $10 to a walk-on cameo for $10,000 — the most taxing was autographing the cast-signed posters promised to more than 5,000 backers. It took several hand-cramping days and constant shuttling of boxes from one signee to the next.

Neil Young loves quality sound and he's willing to pay for it. Turns out a lot of others are, too.

Young easily doubled his goal when fans contributed nearly $2 million in 24 hours to a Kickstarter campaign to fund his high-quality service, PonoMusic. It was an auspicious start for a somewhat quixotic effort the singer has mostly funded himself so far. After initially targeting audiophiles who remember warm sound, Young hopes to eventually draw younger listeners as he tries to right what he considers wrong decisions made over the years when production moved from analog to digital.

Samsung got its money's worth from Jay Z and Kanye West.
