I've owned the same receiver the OP mentions since April 2017. I've been trying to find a software upgrade for it without success, in fact it's hard to find any information about this receiver online, even though it's being widely sold.
It's branded as the "iView C-HD60", but there is no such firm as the "iView" in question, so there is no official website to refer to. Confusingly there is a firm called "iView", but they are not connected with this receiver. It's not exactly the same receiver which someone posted links to in this thread, apart from it not being the SCART model, that receiver has a different front panel and also has a CAM slot. It is undoubtedly made by the same firm though.
I was wondering if the OP was still using the same model and has tried and succeeded in finding a software upgrade for it. In an Amazon review someone claims the seller gave him a link to an upgrade, but he didn't post the link himself.
Sorry for resurrecting an old thread.
