Every couple of seconds the signal drops off (no video and audio) on all SD channels. HD channels are not affected. It's been happening for a couple of weeks and before I would lose the signal after 1-2 minutes. I just did a hard reset (unplugged power cable for 1 minutes) and restarted the box. If first the SD channels were fine but after about 15 minutes the problem reoccured. Has anyone experienced this? Is there a fix? I plan on calling Rogers tomorrow.
