I'm not entirely sure what format (SD or HD) KUIL, KAMU, and KRHD are in as they haven't been added to the DirecTV local channel lookup tool. If anyone in Texas can confirm one way or the other, it would be much appreciated.
The WMVT subchannel in Milwaukee became a simulcast of WMVS (which DirecTV carries on a separate channel) and Vme moved to a WMVS subchannel. There was another WMVT subchannel available that DirecTV could have carried but it is possible they are waiting to carry WMVT HD which is said to be launching in the not-so-distant future.
The Wikipedia article for WDRL suggests it may no longer be available over the air and is only being carried on cable in selected areas. This is why this channel was likely removed.
