KWTX in Waco, TX has CW in downconverted 720p, as their main channel is CBS in 1080i HD. KUPT in Hobbs, NM (part of the Roswell, NM market) has MNT & CW in 720p with Telemundo in 480i (MNT on .1, CW on .2, & Telemundo on .3). KUPT is part of the CW+. So I believe to anyone's knowledge, CW on a subchannel is rarely gonna be in HD, & if it is, will be in downconverted 720p HD (CW typically runs in 1080i HD). Most stations that have CW on a subchannel (in most markets, not enough channels to make it available on the main channel) aren't gonna bother with HD for a small network like CW. The Kalamazoo/Grand Rapids MI market is the largest market with CW on a subchannel (not in HD either), being on WWMT 3.2 (CBS being on the main channel).
