Remote with large buttons for Contour 1 DVR?

Hi,

My elderly Mom has problems seeing all the little buttons on the Contour 1 remote.  I see Cox has some big button remotes for the mini-box, but what about Contour 1?  If Cox does not have one, is there a universal remote with big buttons I can purchase?

We've thought about switching her to Contour 2 with voice control, but there's a whole new menu system and that learning curve might be a bit much for her.

Thanks!
