I am trying to program the remote that came with a new Vizio HD TV to operate my cable box from Cox (Las Vegas, use Scientific Atlanta Explorer 4240 DC). The Vizio instructions call for a 5 digit code, but none of the choices in the owner's manual work. Contacted Cox, but they say they only have a 3 digit code (which did not work).

Codes I tried from the Vizio SV320XVT manual for Sci Atl...
01877,00877,00477,00237,00003, 00000, 00008,00012, 00017,01510

Again, looking for alternative 5 digit code (ideally, perhaps from someone using the same cable HD box?)

Thanks all
