If you got it working with DISH, you'll have no problem with digital cable, it's basically the same setup. Both use the IR blaster to change the channel, just replace the DISH receiver with a cable box.
I'm wondering if Showstoppers have the right codes. And read here somewhere they might be limited to only 100 stations.
Number of stations should not be an issue, but the codes for your cable box may indeed be a problem. If it were not for some great investigative work by someone else on these forums, I would have never known the codes for my amino settop boxes - as they are not listed by replay or tivo, and the cable company had no idea what codes would work.
Thanks for your input guys.
It looks like there is no problem with the digital boxes. All I had to do was look in the setup and found codes for Cox & Time Warner digital boxes. Also a listing for all the stations availiable pops up immediately. It is very simple compared to programming the Satellite boxes.
Sorry for spinning everyones wheels...I should have checked this first
