thanks for asking. I have no Miglia products to try out myself, but 
since it is not an Elgato prodcut, I don't think it is supported:

-- snip -- 
On the hardware side, all TV __products from Elgato__ are supported in 
conjunction with their bundled remote control (currently still except 
products of the EyeTV lines 250, 250 Plus, 300/310, 400/410, 500, 610, 
EZ) as well as TV sticks by TerraTec and Pinnacle shipping with EyeTV. 
-- snap --

If EyeTV supports handing through the events from a remote to Remote 
Buddy, this will always happen fully automatically and "just work". No 
options or setup are available nor needed for this. EyeTV and Remote 
Buddy just need to run at the same time.

Best regards, 
Felix Schwarz
