Channel 93 is a DNS HD feed. Meaning it's a network feed from NY/LA. If HD locals aren't available in your area yet you can call CS and request a "HD DNS Waiver." They'll request a waiver from your local affiliates asking for permission to give you those feeds (it's against the law to turn them on without the waiver). The bad news is the waiver process takes about 45 days and the affiliates don't always grant permission. I've heard that the HD DNS are more likely to be approved though because of some blanket waivers.
