Can anyone recommend a cable that plugs into the Ntl box that splits the signal into seperate video and audio (hopefully digital optical as I would like to get surround sound through my stereo).
Surround sound or Prologic as it's sometimes called only needs a stereo source and can easily be carried via scart or twin phonos there is no need for an optical connection.
If you are hoping to get Dolby Digital 5.1 via a NTL STB then that isn't going to happen for quite a while.
Is there a decent cable you can recommend for rhis?
I have s-video and scart inputs on my tv, but would need a scart cable that splits into separte video and audio leads - I've seen leads that split into 3 phono leads, but would I loose picture quality with this?
A fully wired and screened scart cable between your STB and TV should do the job just fine, even better if you can use RGB.
The stereo sound will also be carried to the TV and output through the TV's speakers, if you then want to feed a seperate amplifier use the TV phono outputs (If it has any) or use a scart cable with additional phono audio outputs.
A scart cable from your STB ending with three phonos (2*audio and 1 video) would indeed reduce the picture quality.
Just checked Maplins , they have the cable I am thinking about.
