Hmmm, if it has the toslink it should be like you said left down to the decoder - which almost makes me want to rush out and buy one.
The almost bit is not to say anthing bad of the box - its just my decoder only has a single optical in, and thats from my sky hd box at the moment - so would need a way of coupling two into one - even an optical switch would be good (but probably costs more than replacing the decoder).
Some more research for me I think
Cheers for the info - seems a nifty little unit.
