RE: sorry if naive - which is best - coax or kat5 ?

["Comm Jo" <commjo2@xxxxxxx>]

Thanks Keith for the info. Very useful - I think I will put loads of cat5
cables everywhere so I can future proof. I will also put some coax so that
I
can have immediate functionality.

One further query - if piping DVD signals - how does the dolby digital or
dts work ?

Cheers

Umar
