Major problems with cable line?

[Jazzie_bee]

I have a similar problem with the HD channels being solid but things like Sy Fy SD and National Geographic +1 having the odd glitches. Not sure if its my wiring or set up. Using CCAM on cable

just get a test line off someone with a decent server, if the test line works fine on the same physical setup that your main line glitches on then its the server at fault ;-)
