Mini box remote not compatible with 2 of my 3 TVs

Here are the problems I'm finding: The URC-2220 for the Mini Box doesn't have many of the codes for popular brands found in other Cox remotes (40 codes missing for Magnavox and none of the 3 codes listed in other Cox remotes for Admiral- both popular brands!). There are even remote codes listed in 2220 manual that are not recognized by the remote itself. The codes listed in the manual but not recognized by the remote are 1080, 1561, 1678, 3492 and 3683. I tried it with two 2220 remotes and both did not recognize the codes. Code Search (Method B) doesn't even go through all 147 codes listed in the manual. I counted it going through about 60. I had to do all 147 manually to find out that no codes work for 2 of the 3 TVs I got mini-boxes for. Is there a Cox Solution to this? This is becoming an irritant to me and I'm seeing its an irritant to other customers as well. If you want analog TV customers to go digital, then you should list all the remote codes that are found in other Cox remotes as well.
