I'd think so. It's on channel 1225 here, but I don't know how similar your lineup is to ours. The channel isn't yet available on the program guide, nor by using the channel up/down buttons; it must be entered directly.
If you can't find it, do what I did: press the blue "B" button on the remote control and search for any of TWC's programs. If you have the HD feed now, you'll see each program airing listed twice: one for the SD feed and one for the HD feed.
