# GB-PVR

GB-PVR was a PVR (personal video recorder aka digital video recorder) application, running on Microsoft Windows, whose main function was scheduling TV recordings and playing back live TV. GB-PVR is no longer under active development and has been superseded by NextPVR, also known as nPVR.
GB-PVR also acts as a home media center software with a digital video recorder, a radio station online tuner, a music and movie player, a library of images and other features.
Although GB-PVR supports open interfaces, the core engine code is closed. However developing personal plug-ins is an option to extend the application and these can be closed or open source, depending on the developer's interests. These plug-ins can be developed in C#, VB.NET or C++ and some examples are available in the GB-PVR official Forums and the GB-PVR Documentation wiki websites. The software was developed with an interface which allows user to change the skin view or other graphic elements as the wallpaper.
GB-PVR is mostly an MPEG recording and playback system, but may also play other non-MPG content such as AVI (DivX/Xvid), WMV, and other formats that are supported by the codecs installed into a computer's.
It requires a supported TV tuner card, a VMR9 capable display adapter (video card), and a supported MPEG2 Decoder. Other requirements are listed on the GB-PVR web site.

## Plug-ins

Plug-in DLLs go in the gbpvr/plugins directory, and plug-in skins in the skin directory. Usually plug-ins are distributed as zip files, and can be extracted to the gbpvr root directory. When there is a skin which is not available in the plug-ins zip file, it has to be copied into the current skin directory.
Some plug-ins may be configured in the GB-PVR configuration tool, but most of them are configured by editing the plugins Manual/ Skin (skin.xml)

## Client/server support

When configuring the machine which is running GB-PVR, the possibilities are client and server mode. The server is responsible of recordings that the clients can schedule. Therefore, clients do not need a recording service. A client PC just can watch TV and recordings from the server, which has to share them. Clients can also use the EPG which runs in the server. There are two different sharing modes:
* Streaming (only supports MPEG2)
* File sharing
Other clients supported:
* Hauppauge MediaMVP
* NMT (Network Media Tank)
