Plugs into the feed from video capturing hardware connected to your computer and displays it on your screen, allowing you to create channel lists and capturing the video feed that's currently being displayed on your screen.
K!TV is a video-capture application for watching TV on your computer. It taps into a video capture device plugged into your computer and displays the video feed on your screen. It also offers some key features that set this application apart from the mere video-capture software. For example, there are several window modes, including full-screen and a no-border modes. You can also capture the video that is being shown on the screen, and, although you can't choose a video codec, you can change the resolution of the recording. The video on the screen may get slow at times, so the developers have included a "simple overlay" function which should make things better.
This wouldn't be a TV watching app if it didn't have a TV guide. So, K!TV uses nxtvepg to display information about your shows in real time. Every time you change the channel, the application displays a summary about the shows that are broadcasted on that channel (as long as your cable provider supports that). If you don't ever change the channel, then the application doesn't display any information automatically. You can still access it manually, though.
K!TV is localized into most major languages, although you are not going to be looking at the menus a lot. The application is rather simple. All you need to do is define what device to use, and then you can simply start changing the channels and watching TV. This is an open-source project, so it is constantly being improved.
