Like to see them fix the Reverse on the HR24-100's, may be happening on the -500's too, but I don't use that one as much anymore.
Often, but not all the time, if I go to hit the 6 sec reverse, it will go black screen for about 3 seconds before showing the picture and playing the video.
Also, once in a while I'll change a channel and I'll get the B;lack screen once again for 3 seconds before the new channel video appears.
I don't know if they are related or not as they don't happen on a regular basis, somnetimes it works fine for days and other times it will happen 3-4 times a day.
Reboots haven't helped.
