That’s one of the details disclosed by web site GigaOm, which found a help page for people beta testing the streaming service that’s due to launch next month — with hopes to challenge Netfllix and Amazon Prime. (The help page now requires a password to access.) To be sure, things could change by the time Redbox Instant By Verizon launches; possibly December 17 based on info on the page. Still, the disclosures are interesting because Redbox and Verizon have been unusually tight-lipped about their plans. The report says they tentatively expect to charge $6 a month for unlimited access to videos. The joint venture has only disclosed one supplier: Warner Bros. But screen grabs show that beta users can access films from Lionsgate (including Killers and Tyler Perry’s Madea’s Big Happy Family), Paramount (Rango, Iron Man 2, and Thor), Universal (Dr. Seuss’ The Lorax), and Roadside Attractions (The Conspirator and The Last Godfather). Last month Coinstar CEO Paul Davis, whose company owns Redbox, told analysts that they’re “getting the content secured” and “making great progress.” Users reportedly will be able to stream to devices powered by Google’s Android and Apple’s iOS as well as Microsoft’s Xbox. For an additional $2 a month, subscribers receive four credits, which expire at the end of each month, to rent DVDs at Redbox kiosks. There’ll also be opportunities to rent and download content via the web.
