This may not be the right forum but I am using XBMC as my main dash. I just purchased a HD TV Samsung 50” HL-S5086W . I am using the HD connections from the xbox to the TV (Red Green Blue) I have optical going to the amp. The problem I am having is there are slight vertical lines when I play games or DVDs on the xbox . Does anyone know what could cause this? It isn’t the TV settings because the regular dvd player works great with an awesome picture. Do I need to change the resolution on the xbox in the MS dash? If so how do I load the MS dash? Any help is appreciated since I bought this TV for watching DVDs on my box.
