It is working in HD on my computer. A one cent cable from Amazon with $4.99 shipping.
EyeTV said it could not be done.
DirecTV said it could not be done.
I done it with the help of the forum folks at DirecTV.
The end of the cable with the red, green, blue, red and white ends. Hm, I looked and thought maybe the two red are not identical. I had them hooked up but got a funky half colored picture. I switched them and HD !!
Here is a shot of my TV and the same pic on my 24" iMac EyeTV
