Bear with me if this has been posted before - it's my first post here. Bear with me if this problem has already been reported - this is my first posting to this forum. I started installing CE's with 57C on my HR34, and that version didn't have this problem. After installing 57D, when playing back a previously recorded program, the audio will intermittently cut out for several seconds, then come back for a few seconds, then out again, etc. The timing appears to be completely random. This doesn't happen for all recordings, but once it starts, the audio will cut in and out every few seconds until I change to a live program. If I then go back to the same recording, it will play normally, sometimes for the rest of the recording, sometimes for just a few minutes and it may start cutting out again. At all times, the video is normal. Also, when the audio cuts out, if I just backup and play back the same area again, the audio will be normal, so it's not related to bad signal causing a dropout.
