From my understand BTV is "suppose" to add several "local" channels. I'm assuming once the "receiver swap" is done and they switch their HD line up to MPEG4 most likely you'll see CBC HD Winnipeg added.Its only a matter of time.
+1 on CBC Winnipeg HD on Bell for the same reason (Jets). And while they are at it they should add CBC Ottawa HD for the Sens games.
However, with the signal finally available OTA in Winnipeg I did pick up a small indoor antenna on Saturday at the local circuit city and connected it to my 9242. After a quick scan it found CBC Winnipeg HD and I was able to watch the 7-1 thrashing of the Jets in full HD through my Bell receiver (with PVR functionality).
