DTV sent me a R22-200 DVR as a replacement for my old R16-500. I can't find a setting anywhere to format the video output for my widescreen tv. I do not have (nor want) HD DTV service, but I do prefer that the picture not be in a little box in the middle of my screen. The aspect ratio setting in the Display / Video menu won't let me change it from 4:3 to 16:9. I can see that option but it won't let me select it. The R16 output looked fine! My TV is a fairly new Vizio widescreen Any tips on how to get this thing to display properly?
