I've been seeing this issue for a few months now. Often (but not always), a DVR event will start one minute late. I double checked my settings and my default setting is to start 1 min early. This is not due a schedule conflict. It will happen with the unit powered down and only one event scheduled. If a program is set to start at say 12:30, the DVR will show that it actually started at 12:31 rather than 12:29. I do not see any other threads about this. Is anyone else having this problem?
