I have noticed this several times in the last few weeks that my recording light comes on for a super short time on my HR23. It is such a short time that it does not get fully lit and then it is gone without me doing anything. When I check there is nothing recorded. I even have checked to see if an extra one of those banner ads has been loaded but it hasn't. My DVR is not giving any kinds of problems. Does anyone know what it is doing ? Thanks.
