Nearly every time I try to sit down to watch a film or show on itunes or Netflix, the program will start out fine and within about 10 minutes or so, will abruptly stop.
Your experience is not that uncommon. In order for a movie to stream smoothly, and uninterrupted, a fragile and complicated network must work perfectly.
Try power cycling your router. I find that sometimes helps. (Do this when not downloading.)
Check your internet download speed, you can do this at, www.speedtest.net.
1080p requires 8 Mbps, 720p requires a 6 Mbps, 480p requires a speed of 2.5 Mbps. I have 85 Mbps, and do not always get smooth, uniform, playback.
But, there is good news coming!
Technology experts are working on a movie storage system where YOU have physical possession of the movie.
This system stores the movie digitally on an optical disk system that will not be dependent upon a congested, complicated, and fragile network. Because all of the data is stored only a few feet from your television, all the bottlenecks are removed. Performance and reliability are virtually flawless.
Further, the system will not utilize any form of security codes, authentications, or passwords. Once the optical disc is purchased it can be moved around freely at will, and can even be lent or given to friends and neighbors with zero hassles. And if you don't like the movie, you can sell it for close to your purchase price!
