I have not seen this condition described by others. While watching a recording the picture will go blank with no sound as well. It may happen for just a few seconds to maybe 30 seconds. The recording is ok because when I go back it plays properly. It generally happens several time per recording for different intervals. It only happen on programs recorded on the family room hopper, but it happens even if viewed on the master bedroom hopper. If I record on the other hopper it doesn't happen regardless where viewed. Has any one heard of any thing like this. It is a fairly new install about a month but I didn't have the problem originally.
