Alright, I made 1 and 1 make 2 here. The new silver remote from Comcast requires a 5 digit code, and none of the above provide that. However, I tried the codes for Orion and the code 10463 works, (recognize the 463 and 0463...). I have a 21" Insignia from late '07. I would try the rest of the Orion codes and the Emerson codes and they should bring great amounts of happiness while we cater to our indolence with minimal remote controls and no getting up to change channels/power the TV.
