You can load the homeworx fw and get it to work. There are even multiple videos in the Homeworx thread showing you how. However, if you do not have either a homeworx or harmony remote and are not sure you're going to be able to get the xbox working properly with it, then I would advise against it since you will no longer be able to control the box with your iview remote.
If you want to load the firmware, you have two choices - the one for the old box or the new box. You can find v10 (for the old box) in the HW thread in one of my posts where I uploaded it. This version does not have a dash key and will not work as well with the xbox one guide on the single digit channels. If you want the dash key, which works better with the one guide, you can load v14 (for the new box and new remote). I'm not going to link to it here but you can find the file in the xbox forums (not on avs, on xbox.com). I found it quite easily with the first search I did. Since it's not my file, and I don't have my own copy of v14 to compare it to, I cannot personally vouch for it's integrity. To get an official copy of v14, you would have to email mediasonic. They will give it to customers but you are not a customer of theirs so I will leave that between you and them.
As for the IR codes, like I said, I don't have an xbox one and do not know if your remote is programmable. That is something you should already know or easily be able to find out. I've already done enough research for you really. If it is programmable, you can program the iview IR codes. How you do this would depend on the remote and how microsoft has designed this function to work.
Sorry for the delay in the response ... it worked!
Now it's all starting to make more sense. (Sometimes it's tough for a newbie to piece all these puzzle pieces together, so thank you very much for all the help!)
