you won't your home cinema amp every time you watch TV through the Virgin box , so hook that up to the TV as you have been . however when you do want your amp to output the TV broadcast sound then connect the Virgin box up with a Optical or Coaxial lead . if you want 5.1 a simple phone lead will not suffice instead of a coaxial lead .

Why?

I have my 7.1 system permanently hooked up to my sky box, PS3 etc, I didn't even bother to order the speakers for my tv.

Fixed that for ya.

All digital leads are made within certain tolerances
Poor toslink connectors (Thats the cheap cr*p that YOU buy) are the main culprits of causing jitter

Its fibre optics over minimal distances there is no loss, I'm sure the tolerances will come in to play over 1km but with interconnect cables its simply not an issue, as long as the ends are spotless when plugged in all is well.

and its funny all the trade cable I buy states attenuation figures but I can never find it on these "hifi" cables, that space on the spec sheet is filled with the flowery words, which is great for analogue, nonsense for digital.

If you are going to be swapping them around a lot then maybe look at the build quality of the connections but no more than £10 retail.

Assuming that's true (it's not), how exactly does the jitter manifest itself in terms of the picture quality? What differences in the picture do you see (or think you see) between the cheap and the more expensive cables?

Toslink is audio. Jitter is the packets of data arriving wrongly spaced and can be measured and buffered.

OK, what differences do you hear? How does it sound different?

It doesn't really if your converter has the capacity to cope, and recent equipment has.
But missed/wrong packets can pop, click etc..

I'd just be wasting my time wouldnt I

Also, toslink is AUDIO ONLY
I think youd better go do your homework first mate...................

TOSLINK isn't audio, it's optical. Red light, not red light, red light, not red light, representing 1 and 0. As with other digital carrying cables (network cables, phone cables, HDMI - bandwidth tends to be more of a problem than actually having a fuzzy/unclear picture. So your CD might work OK over cheap TOSLINK, but 7.1 DTS might not. SkyHD might work over then cheap HDMI cable, BluRay might not. If you haven't encountered any problems with your cables, good for you, stick with them, they're doing the job. But if you get a jumping picture, clicking sound, or a blank screen, don't come crying to us...

Toslink is for audio streams, its quite clear in the discussion why this was being stated.
If you didn't read the previous poster was asking about picture quality with toslink cables.
