Replaytv 5000 and Humax HFA100 OTA

I searched around and I didn't find any posts on this.
I have stumbled on a few Humax HFA100 OTA boxes, they have HDMI, Composite Video and RGB output

My Replaytv is connected to Directv now, but I am probably going to get rid of that, and I will have basic cable which works with the ReplayTV and OTA which obviously doesn't.

I was going to try some of those CECB units I have collected, some are known to work with ReplayTV.

But these Humax units are probably better. Not coupon eligible, they were before that I think.

I found the remote code files on the JP1 Lookup.

But I need this to work with ReplayTV, if it can without going through conniptions.

I have to say, on the ReplayTV the recorded Directv signal looks much better than the signal recorded off analog cable. Amazingly better, really. Not HD but quite pleasant.

Has anyone tried this box? Is the remote code something that is already in the ReplayTV, like the Channel Master CECB was and the RCA CECB was?

Thanks in advance.
