I get intermittent picture and sound problems when watching or recording using the Youview box however there are no such issues when the Youview box is bypassed. I have checked all cables and reset the box. Any advice would be grateful. Thanks.
Post the signal strength & quality figures for any of the channels giving you issues, assuming we're talking about normal Freeview channels.
Yes normal freebies channels. Especially BBC 1 and ITV 1 on both standard (channels 1 and 3) and HD (channels 101 and 103) versions.
Whenever I check the strength and quality they are both at 100% which why I am very puzzled.
