I have Ballstreams and recommend it to anyone. The service and product is phenomenal. Prior to that I used to use a service called Playon. Playon allows you to add third party plugins to stream games. The quality is fair for streaming games but you do not have to worry about viruses or ads etc. Also, Playon has many plugins that allow you to watch current tv shows, movies, etc and they do offer them in hd. I have a lifetime license and now use the service to watch movies and the Giants when they are blacked out in my area. The lifetime license is being offered for $24.95 for the holidays. It might be worth checking it out even if you used it in place of Netflix etc.
