DISH uses standard DVB protocols making it easy to do uplink reports, while DIRECTV uses its own private propitiatory system to transmit and continues making changes to it system which make doing an uplink report near impossible to be accurate.
(Update: I received a note that Sixto does not currently work for DIRECTV. If someone is in the know of the DIRECTV datamap and would like to help us build an automated DIRECTV uplink report system please let me know! We would love to add this as a feature to the site!)
