Samsung UN40ES6100 Universal Remote

I just purchased a Samsung UN40ES6100 which came with a Universal Remote which includes the buttons needed for the Smart TV. I was able to get through the Universal Remote Setup successfully. I can navigate the channels, change volume, go the to the menu all for the cable box, but the one thing i can't do is access the guide. I have Cox as a service provider and a Motorola - CMH3200 box. Is there anyway that I can access the guide from the universal remote. If not this means that I have to use two remotes on a daily basis? One to access the TV and its smart features an another to access the guide which i use on a daily basis. There has to be a way to access the guide. Both Cox and Samsung just keep saying if it is a universal remote all features may not be available.

Any help would be greatly appreciated.

Thanks!
