This would be invaluable for myself, as I'm stuck with a defective unit, but given I'm in the UK I can't afford to ship it to America and back just to get it repaired. In my case, it thinks my Component YPbPr cables as Composite/S-vid, and none of my TVs accept the signal (I have to use my XRGB-mini). Here's an image of what it looks like when using the Component cables running through the XRGB-mini https://i.imgur.com/1DloQlt.png
I straight-up can't figure out what it thinks my Composite/S-vid cable is, as no TV I have, nor the XRGB-mini, will accept it.
I've tried all varieties of sync and standard, but have just had no luck getting it working properly.
