Hi,
I would contact your local engineer to acertain what type of stb-c your tv has.
I too have a Beovision 3-28 and the first time I had the stb-c updated the engineer was amazed to find that it was a software update, via a laptop, rather than a chip upgrade. If your BV3 is a software update then the engineer can simply put together a list of your requirements from the complete list of available stb codes.
I had mine updated recently with a selection of UK boxes: Samsung T351, Apple Remote, Microsoft Xbox, BT Vision, Humax HD Freesat, Sky Digital, Pace Sky+, Topfield TF5800PVR, Topfield TF5810PVR, Thomson Sky HD, VirginMedia V+ and Sony Playstation 3.
Hope this helps,
Downtime.
