KXRM and the CW

I've had a few calls wondering why Colorado Springs is currently getting the CW on both Channel 57 (KXTU, channel 7 on Adelphia) and Channel 20 (what used to be WB2 out of Denver). KXTU is supposed to have the rights for the Springs as the local affiliate and GM Steve Dant says he's working on it.

Given that Comcast is still using the Adelphia name in Colorado Springs, apparently just to confuse as many people as possible, I won't be surprised if we have two CW's for some time to come.

Also, given that KKTV/Channel 11 is trying to squeeze high definition programs from MyNetworkTV in alongside high definition programs from CBS, I wondered if Dant had thought about putting the CW in HD on KXRM/Channel 21's digital frequency. He said they'd talked about it, but haven't had time to see if it's really possible (both stations are owned by the same company).

Fox, KXRM's network, broadcasts HD in 720p, which takes up more bandwidth than the HD format CBS uses, 1080i, so there may not be enough bandwidth to go around. It would still be cool to see "Veronica Mars" in HD.

Hmmm.... re-reading that, this is one confusing post. Hopefully, it makes sense to someone other than me.

UPDATE: In comments, Tallguy says he thinks 1080i takes up more bandwidth than 720p. I looked around a little, and near as I can figure, it comes down to the compression scheme -- that either one could take up more or less room than the other depending on how stations configure things. Anyway, CW on a subchannel is just an idea for now.
