I have used the Raphael cable for this excercise as I like my old Hermes one better.
You will need:
One Red White and Yellow RCA Cable
Step One. Remove pin four from the extUSB plug. *note this can be tricky but is necessary to allow the device to recognise the cable as a TV out cable as opposed to a Headset cable. I used a needle to bend into the middle of the plug and then used a tiny micro screwdriver to bend backwards and forwards until it broke. Be careful not to damage any of the other contacts. Please see post 20 for an easier option that doesnot involve removing pin 4
Step Two. Cut cable as close to mic piece as possible and remove outside cover.
Step Three. Solder the following pairs of cables together using the following codes:
Video positive (Yellow RCA end) --> White pvc coated cable (extUSB end).
Video sheild (Yellow RCA end), --> blue copper cable (extUSB end).
Audio Left (White or Black RCA end) --> green copper cable (extUSB end).
Audio Right (Red RCA end) --> red copper cable (extUSB end).
Audio Sheild ( both Red and White or Black RCA end --> copper cable (extUSB end), * note the copper cable is the sheild wire that surounds all the coloured wires.
The last two colored copper wires
Step Four. wrap electrical tape around the solderd wires so that they do not touch any of the other contacts.
Step Five. Plug in and play.
I think the device must have the TV out function cooked into the Rom or maybe there is a registry hack?
