Conclusion: Very surprised to find that the picture quality was very good in general and brilliant for the price. I have used various PC TV solutions over the years and didn't think I would get this image quality for less that Â£100 but it looks as though I did. Fast moving images (i.e. scrolling titles after programs), are blurred but that may also be due to my monitors. The image quality is far superior to Video but not quite so good as DVD.
Summary: Ordered yesterday. Got it and installed today. Windows 7 recognised and installed drivers automatically. Fired up Media Center which identified the Freesat channels, downloaded the guide. Installed GimmeITV HD. Picture quality excellent (that is on a signal quality with only 6 bars out of 10.
All flawless except for one gripe: the satelite inputs at the back of the card are too high and a bit too wide, making fitting of the card very tight.
Conclusion: This card works great on Vista HP SR1. The software supplied works but it works even better if you use DVBViewer V4. I have all the Freeview satillite channels but you must use software that allows the selection of a H.264 codec for HDTV, ComproDVT 2 does not, DVBViewer does.
