Its getting annoying.. Both my DCX3400 boxes lose picture for approx 4-5 seconds, sound continues to play and then picture comes back on screen..
I have come to the conclusion that this is not a issue with the TV, Receive, Cable or anything else..
It is an ISSUE with the DCX3400 Comcast Box itself. I think Motorola needs to address this issue..
If you have this issue please post here. If you have a solution.. please.. please let me know!
