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

["Gareth Cook/STA/Lotus" <gcook@xxxxxxx>]

If you used TOSLink to distribute the
signal, you can get lengths of up to 10 metres quite cheaply. Maybe you can
get an optical repeater for longer lengths ?

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
