For a few days, now, there appears to be signal problems - particularly with the H2 channel. Every 5-10 seconds, pixelation appears similar to this: How to troubleshoot poor picture quality / pixelation or sound clipping occurs. This is also occurring on other channels as well, but I haven't done extensive research on how many channels (for example, it happens on H2, Slice, and DTour, but I am not seeing it on the Food Network, Lifetime or HGTV). Because this isn't a universal issue (i.e. on all channels), that indicates to me that there may be an issue no Shaw's end?
