I have been using the Gateway for 3 years now and have had this problem with some American channels that are mirrored on Canadian channels, but this time it was on Showcase and there was no other parallel broadcast. I had just spent almost two hours watching "Supercollider" and we were running about 10 minutes behind the live broadcast. Then, just before the movie ended, it bumped to 8 minutes into the following movie "300". The buffer was reset to zero time as well so there was no way to either catch the end of the first movie or even the start of the second.
What is going on Shaw? This is crazy.
