I have had this problem ever since switching to bluecurve a year and a half ago. It clears up for a while and then it starts up again. I too have spent time on the phone with their phone techs, I have rebooted the tv boxes, moved the modem to different locations in the room and nothing works. Obviously Shaw does not seem to make resolving this issue a priority and when my two year obligation is up I will explore other options.
