I am receiving several DMS-2002U DTA boxes from WOW! Cable.  It appears to be made by a company called Evolution Digital.  http://www.evolutionbb.com/ebb/Universal-SD-DTA/subpage447.html

I think that the Cisco DTA50 might be a re-branded version also, not sure.

I would like to setup my MythTV box to control these boxes.  I am hoping that I could get help from you guys to get that working with lirc.  I can not find any info on what IR commands the box/remote use.  Has anyone come across this device?  Does anyone have a remote file for it?
