Yep they are quite cheap - around $10 here (£5) - quite strange as the fibre optic cables cost alot more.
The bit always missing from my google search was TOSLink - I was not aware they were refered to that before you post - so thx for that.
Oh by the way - I am going to blame my forthcoming expenditure on yourself - cause if it was only stereo I would not have bothered - now I need ummmm
1. WD TV HD
2. 2 Terrabyte Disks (Lets not do this by half)
3. 1 Optical switch.
4. 2 Optical Cables.
Make that 3 optical cables as now I can do the PS 3
Could you PM your phone number so I can get her to nag direct ?
