They were given the excuse that Destination America is trying out new programming in the time slot.
Original: Destination America has dropped the first airing (8:00 PM EST) of Ring of Honor TV on Wednesday nights. This Wednesday night the network has Bigfoot in America in the 8:00 pm EST time slot, which ROH is usually in. The following week (8/5), the network has Mountain Hunters listed.
So it appears that this is not a one-time deal.
