I was a little concerned that I would have problems having read some other reviews. I needn't have worried and I wonder what other buyers have been doing to get poor results. I wanted this to be able to watch TV while working at the computer.
The device is very small and the installation manual is actually very good for such a product. My advice - READ THE MANUAL and note what it says about aerials! This device is only going to work on a good aerial so, if your TV has problems, so will this device. I'm running Windows 7 and I did not need the supplied drivers as W7 found them automatically from the Internet and installed the divice perfectly. After installing the TotalMedia software, it took a while to tune as the tuning is very slow compared to a STB but, once done, it worked perfectly. Use the LCN option when tuning and then sort by LCN to give the same channel numbers as a STB or TV would.
Quality is excellent, even on my 1920 x 1024 monitor so I'm extremely pleased and would recommend this product to anybody. Please note: Don't buy this or any other similar device if you want TV on the move. Throw the supplied aerial away!
