"ColorStream" is nothing more than Toshiba's trademark name for their component video interconnect- it shouldn't function any differently than and other standard component interconnects.
What model is the Toshiba TV?
I have a Toshiba TV that is not HD, but does have what appears to be component inputs. The Red, Green Blue on the back. However, in my Toshiba manual it states that this input is called Colorstream. Nowhere does it mention what we traditionally just call component inputs.
Now I tried to hook up my Nintendo Wii to my TV via component cables and the image displayed all distorted, but as you see in scrambled TV channels. I tested the Wii on an HDTV with components and it worked beautifully.
Does anyone have any input on this at all? Is the Toshiba colorstream something other then component input, or is there something I need to adjust that could get my Wii component inputs to work on it?
