The DCX3400 actually responds to two different IR protocols-- General Instruments device 0, and XMP device 62.16.
The Comcast supplied remote sends the XMP protocol (setup code 01982) which can be quite difficult to learn. Jason provided the GI IR protocol, and the Pronto Hex above is also GI.
If you want to exactly duplicate the IR protocol being sent by the Comcast remote, I can provide those Pronto Hex codes. I'm not aware of any particular reason to use XMP rather than GI.
3FG - I would appreciate any more of the pronto hex codes. The three on this page seem to work perfectly for my DCX 3400. The ones referenced in the other thread post 11 and 16 do not work at all.
