There are several advantages of using USVideo over StrongVPN, HotSpot Shield and other VPN based or proxy solutions.
USVideo works with media players such as Roku, Apple TV, PS3, XBox and others, while VPN based solution works with computer only
None of your video/audio content or unrelated traffic goes through USVideo, therefore there is no bandwidth loss, data cap or privacy concerns.
Simpler setup, VPN works only on computer, so you need to setup it on every computer in your home.
No software to install.
Your IP remains your local IP. This may be important for other sites that you want discover your correct Geo location
Content from different countries is streamed transparently - no need to switch VPN
What about my privacy and security?
You're sending all DNS requests to our server, but we're changing routes only for sites we support.
We're trying to limit amount of data sent through our system (we're paying for every byte) and redirecting only sites directly involved in location validation.
This is much more secure than VPN or proxy solutions, where you have to send [almost] everything through their servers and you will never know what they do with this data.
DNS solution is more transparent to users and everyone can verify where data is being sent by comparing results returned by our DNS with "standard" DNS responses.
Most sites with somewhat sensitive information are using SSL encryption to protect users' data. Even if we were redirecting these sites to our server, we can't "fake" SSL certificates without being noticed (you'll see security warning in the browser when site certificate does not match with name), and wouldn't be able to see encrypted data.
Again, comparing to alternative solutions, if provider require special software installed in client's systems, then this software can either install "fake" certificates or "sniff" other users' data (e.g. passwords, credit card numbers, etc). Our solution does not require any special software, changing permissions or other potential security risks
