I'm surprised they didn't clear up this mess between the two units. I complained and got $20 refund. I hadn't really intended on using the card system. Rather, I just wanted the blind scan.
It might help if you attached a photograph of what your were sent. The new 2104D looks like the old 2104C with the exception that it has no ventilation holes on the side of the box and there is no LNB output. I believe it works slightly better than the 2104C, so the chip set could be different.
While you can blame DVBWorld for their attempts at English (which are probably better than my attempts at Chinese), an importer should really do a better job of presenting the product. China is where you commit fraud, violate patents, etc. It is a lawless country. However, when you sell Chinese products in the US, all the liability in on the US distributor.
