Chris,
what I was wanting to do was to use a device similar to the one you linked to to insert new audio into a HDMI video signal which already has embedded audio, without having to first remove the original audio somehow. I'm hoping that such a device would simply 'overwrite' the original audio bits with the new ones.
Aron,
The original is on a Blu-ray disc, the replacement audio is on a USB stick. The video loops continuously, it's only about 4 minutes long. It's made from still photographs of some artworks, with the artist talking about them in Czech. She has recorded the new English version, and if I trim it to exactly the same length as the video and play it on my loptop it stays close enough in sync with the original video; there's no lip sync on it.
I was planning to take the English audio from the laptop, and insert it into the video from the Blu-Ray player, but maybe copying the video from the BD onto the laptop, replacing the audio there, and then playing the whole thing from the laptop would be a better idea. I can't write Blu-Ray disks, but I could run it from the hard disk. There's no HDCP involved. The laptop can output HDMI with embedded audio which I could feed into the distribution system.

I guess both methods will work. However, if you substitute the audio based on a digital files on the laptop, it may be converted into a new DVD or BluRay or HD playable file for repeated use. You would have to get a BluRay Ripper and drive somehow, somewhere. It probably could be captured digitally as well, a BluRay like this may not have copy protection set, thus HDMI capture might be possible.
You will have to ask around what type of gear will possibly be available for no or low cost.
In the long run, a solid method for BluRay Rip or capture might be worth the money more than having a rather special device like an HDMI embedder in your gearbox - if that is a useful consideration for you.
Of course, IF it works, the embedder is the easier and faster solution.
