Looking in the file urmgui.xml, I noticed a couple of xml tags: vendor and model-name. I believe these are used by the pc software, but may not be fully implemented. Hopefully Sony will provide future updates to enable users to select a model name as an option for learning the remote codes.

You would think that Sony could at least support their own products on the remote. My multi-disc dvd player (Sony DVP-CX985V) was recognized as a DVD-R so I had to learn a majority of the remote buttons one at a time.

My receiver (Sony STR-DB1070) did a better job, but there still was some button learning to do.

Overall, the RM-AX4000 is a huge improvement over the one I had before (RM-AV3000). I hope Sony keeps improving on the software and firmware.
