Thanks everyone for your advice and photos.
I am officially at the end of my tether now! I have tried all the suggestions and the best I can get using the component cable is sound and no picture. With the added bonus of dreadfull intermitent feedback coming over the speakers.
Rico, I have the same setup as you connection wise other than using VMEM instead of DVD I assume this would make no difference?
JK I do not have another component device to try unfortunately.
Just to clarify the procedure as far as I understand it;
When connected via standard cable I can select the screen menu as above, I then hover the cursor over HDTV/EDTV box (which is grayed out) swap cables to the component, thus losing picture. I select the box, hear a click and then move the cursor down slightly to click on conirm, hear a "bong" noise.
Having done this what must be 100 times now I have tried with swithching the TV off and on, the wii off and on, both off and on both on whilst hopping on my left leg blindfold. All to no avail!!!!!!!!!!!!!!!!
Anyone any final suggestions ?
The Nintendo wii helpdesk state the problem may be because I am not using the official wii cable, even though the Gameware one I have is licensed to use their TM. the technician states the wii can detect the resistance pulses up and down the cable and if "it" senses something wrong will not open the required software. The retailer who sold the cable state they have sold 1000's and never heard of this.
