Interesting that they are switching the SD feeds to Eastern from Pacific, never figured out why this wasn't done from the beginning. It annoyed me when I'd see something I'd want to watch on SD, only to realize I had missed it in HD.
Quite honestly, in this day and age I am not even sure why they bother keeping SD feeds of things. What annoys me is the lack of a HD CW feed. I lived in Alberta previously and had Telus Optik and they had all four "superstations" (WGN, KTLA, WPIX and WSBK) in HD. Going to Sasktel where they only have WGN, which has disaffiliated from The CW a couple years ago is annoying. Plus, I like watching police chases and things on KTLA, so HD is better for that.
