Guide to Installing GB-PVR
Thursday, 12 February 2009 00:00 | Author: Paul | 
GB-PVR is a free TV and Multimedia centre for Windows. I prefer it as it runs on Windows XP Pro (my preferred flavour of Windows at the moment).
It can record TV programs, stream TV to other PCs on your network and be used to view and manage your photos, videos and music.
If you use your PC with a large screen or TV for multimedia - then GB-PVR is well worth exploring.
The catch is that it can be a little tricky to install for the first time - but once successful, you'll be glad you did.
This is a very good and easy to follow guide here
