Recently I bought yself a new TV, one of the features was that its Internet enabled, and like a modern smartphone has a series of apps.
It being a TV there are obvious video related apps, like Youtube and Vimeo and some less understandable applications like Twitter and Facebook.
One application was Love Film, I signed up to the steaming trial. They have 6000 films mostly older ones. The quality is nothing to write home about all standard definition they can look fairly ropey with a lot of pixelation. Still when there is nothing much on TV its fairly easy to find a decent film. Its a subscription service, so has a monthly fee though there is a free 16 day Trial.
Another app was Ace Trax. This is a pay per view service which lets up buy or rent content. They were offering one free rental, so I very slowly registered (using my tv remote), it was painful. Then I choose a film went to my movies and attempted to play. This first attempt froze the app. Second attempt stuck at buffering for 20 minutes before I gave up. I had one more go this time I saw one second of fotage before it froze. At this point I gave it up as a bad job.
I guess for the moment the only way to download films is to pay Virgin media pay per view. They are quite expensive (more than actually going to blockbuster), but at least their app works and the quality is reasonable.
I really think that there is a gap in the market for a good quality app that focuses on the user experience and has a decent range of films to capitalise on the non Apple user. Hopefully someone will take up the challenge because the state of streaming today is woeful.
