Netflix is by far the biggest video streaming service but users like it the least of all the services covered in Consumer Reports survey out today.

Just over 8 in 10 in the CR survey who used a streaming service the previous month subscribed to Netfilx, but rival services Vudu, Apple iTunes, and Amazon Instant Video all scored higher in overall satisfaction in the consumer group's first ratings of video services.

"Our survey revealed that a healthy selection of titles is one of the biggest factors in overall satisfaction with video services, which is why disc rental services and pay-per-view streaming services scored the highest in our Ratings," Jim Willcox, senior electronics editor, Consumer Reports, said in a statement.

"Streaming video content directly from the Internet is emerging as the preferred choice for video viewing," according to the magazine. "Fifty-two percent of the 15,277 ConsumerReports.org subscribers polled said they used a streaming video service in the previous month, compared to 47 percent who saw a movie at a theater, 43 percent who rented a DVD or Blu-ray disc, and 32 percent who used their cable provider's video-on-demand service."

Netflix users griped about its limited selection of movies, especially new ones. Fewer than one in five survey respondents said that they were highly satisfied with the unlimited-use services' choices of titles including those who rated Amazon Prime and Hulu Plus. Pay-per-view streaming services including Amazon Instant Video, iTunes, and Vudu did get high marks from more than 60 percent of users, the group said.

"Netflix's disc-by-mail service and independent video stores were judged to have a more satisfying selection of titles, including current ones, than even the best streaming services. Redbox kiosks were neck-and-neck with Netflix and independent stores in overall satisfaction, but fell short on selection. Survey respondents were not as impressed with Blockbuster stores, Blockbuster Express kiosks or Blockbuster Total Access disc-by-mail," according to CR.
