I tried to use a wireless video sender a few months back, for fairly obvous reasons, and had one or two problems with it 1) NTL remote did not work in the second room. it looks like there are a couple of products on the market now that fix that one - DigiSender Gold X4 ; One For All SV1720 . Is either of these better than the other? 2)The picture did not alyays remain 'steady' - is it realistic to expect good quality in the second room - good enough to video for example? 3)......... and this is why I took it back. Whenever we used the microwave, we had interference. Are the frequencies too close? Will microwaves interfere with the 2 products listed above? Comments pls folks?
