I am having the same issue, the only difference is that the extender seems to be receiving the commands but it doesn't pass them on to the IR ports. The only way to resolve the issue is having to reset the RFX9600 by pulling out the power.

Any thoughts on what might be causing this issue?

By the way, it happens only after using the remote for while and especially watching recorded shows and having to scan forward or reverse to skip commercials, etc...

I appreciate any thoughts on this.

Thanks!
