We have had D-10's (owned) for years without any trouble. During our recent move, one died. So we decided to "upgrade" to a R-16 SD w/DVR. Like it so far and have noticed the channels we don't get are grayed out. Yes, no surprise to most of you, but we have been content with what we have had. We really like this grayed out feature, and wondered if it is possible with a software update on our D-10's??
