If you are looking for something that is compatible with your Linux operating system, that will be able to record TV, allow you to watch, fast forward, pause, and more, you may want to consider MythTV. Basically, MythTV is a digital video recorder, very similar to the one that you may have with your satellite or cable television. The difference is that this program is open source, and usable with your Linux operating system.
With MythTV, you can not only watch movies that you already have on your computer, but you are able to also watch live television. It is the free, open source alternative to programs such at TiVo or Windows Media Center. There is so much that you can do with MythTV. Not only can you watch television and DVDs, but you can also store your pictures, and watch a slide show of them. Music is compatible to store on MythTV as well.
Originally, MythTV was created in 2002 as a better way to be able to view cable television. It was created at first, to only be compatible with the Linux operating system. At this point, it is also usable on BSD and Mac OS X. Very recently, it has also been found that it may be possible to soon make a version of the software for Microsoft Windows.
The front end, or the interface that you use, allows you to decide what you will do with the program. It even gives you television listing guides. If you want to see what shows you have recording, you can easily do that from the front end, as well.
If you are looking for a system for your computer that allows you to watch your videos and television, even in high definition, check out MythTV. You are even able to split what the program is doing for different locations, so that it works best for each task.
