I'm sorry to hear that you're having a hard time finding the codes.
Unfortunately, Comcast or the box manufacturer controls the code bank assignments for their boxes. I just don't have a list of codes that they've assigned to specific Samsung products.
I had to get a new Comcast DVR-3 Silver Remote control this week. I had my previous Comcast Remote programmed using the aux button with code 1932 for use with my Samsung HTIB.
The new remote appears to be exactly the same, except it now asks for a 5 digit code. The instructions that came with the remote don't list a HTIB code section like the instructions for the old remote did. I also tried using the code search function, with no luck.
I called comcast and they were no help.
Does anyone have the 5 digit code for Samsung HTIB?
