Roku remote not controlling Insignia TV

I heard back from Insignia.  Here is what they said:

Thank you for reaching out to Insignia. My name is Carl, and I’m here to assist you with your Insignia - 32" LED 720p HDTV (NS-32D312NA15) issues.

Upon reviewing your question, I understand that you want to program your Roku Stick remote to control an Insignia TV. Unfortunately, it is not possible to use a Roku Stick remote to control an Insignia TV directly. The two devices use different operating systems and remote control protocols, making them incompatible for direct control.

I guess that's a dead end.  Obviously Roku remotes control some Insignia TV's.  I assume they are talking about my specific model.  Looks like I'll just use two remotes.  Anyway, I thought I'd post this here to let others know what Insignia said.   Appreciate everyone's assistance.
