Like i said i have a Comcast Motorola DCH3416 HD Dual Tuner DVR and am having a problem changing from SD channels to HD channels. For example I used to be able to go from a SD channel in 480i and switch to a HD channel at 1080i and the video would automatically switch from 480 to 1080. Now it doesn't switch and you have to press the format button on the dvr to manually change the video format. I don't know what happened but how to i get it back to where the format switched automatically?
