I personally find CNN's US-centric broadcast to be rather mind-numbing. Is there any chance we could swap it for the BBC's more worldly view? [Hope this suggestion does not offend anyone.] It would also be a popular move for many of Rogers customers if something like TLC could be swapped for CTV's Sci-Fi channel.
Perhaps you could do a poll of folks on the Community Forum.
One of the nice things about Ignite TV is that with Flex Channels, you can (to a certain extent) dump channels that you don't want and swap them for others that you do. (Of course, more Flex Channel choices in the lower tier bundles would always be welcome!)
