If you're not familiar with the TVU Player software then the short version is that it's a web browser and media player for Windows that you can use from the internet. The problem is that you can't use the software to stream your own media files and this makes it something of a niche product. However, this software has a lot of potential for anyone who wants to access movies and television shows through the internet but doesn't want to pay for subscription channels or pay for a TV satellite dish. The fact that it is web-based means that it isn't subject to high tariffs that would prevent people from accessing it online - this means that anyone can use the software without limitations.
The software works by connecting to a windows server. This server is accessed through a special browser that lets you browse through websites and download files at any time. It works by turning any file you download into an HTML file. Then it redirects this file through your internet connection to a TV guide on the computer's hard drive. Once the content has been changed then it's then played through the Windows Media Player application. However, unlike other software programs that are web-based, TVU Player requires that you have a Windows PC because it needs to access a windows registry which is only accessible from a windows machine.
Unfortunately, you cannot play your media files on the TV. However, this does not mean that you can't watch or download videos. There are many people who claim that they use the player in order to watch live broadcasts but that they only use it to download media files. To use it as a media player, you need to use an appropriate media player. If you do this then you can access live broadcast channels but you can't use it to watch free TV online.
