Has anyone created a renderer profile for a CA Azur 751BD?

HI All,
I'm new to Serviio so please be gentle! I've recently set-up Serviio on a Synology DS212J - the whole process of setting up NAS and Serviio was pretty painless, and by and large I have everything working how I want it to. I have a library of MKV video files with h264 HD video and DTS core audio and by and large these play back fine on both my Cambridge audio Azur 751BD (using generic DLNA profile) and my Sony BD570 (using the Sony BD profile, via transcoding). For the files to play on the Sony I have had to select to down-mix the audio to stereo, but that's OK because it's only connected to a TV.
The CA is my main player and I have a strange issue with a handful of files. Basically some letterbox format movies get stretched (vertically) to fill the whole screen. I've analysed files that suffer from the problem and those that don't, and there is absolutely no discernible difference in the video content of the 2, but nevertheless the issue occurs. I've narrowed it down to the CA by testing with other media players. I have raised it with CA support who are looking at it
I've experimented with other renderer profiles with not much success (as you'd expect, but I figured it was worth a go), and I was wondering whether a specific renderer profile for the CA might sort out the issue? Has anyone out there got the Cambridge and created a profile? Or is that not likely to resolve the issue? I'm afraid I really am not proficient enough to create one of my own, so I have to hope that someone out there has already done so.
Many thanks
Dan
