There's certainly nothing magic about an STB, they are built with commodity 
hardware and, with the exception of some DRM schemes, fairly well-known 
software techniques.

I can't see any obvious reason a commercial STB would "always" (be careful 
with that word) deliver better results than any other solution that uses 
similar hardware and software, unless of course some market force has 
intentionally "dumbed down" a non-STB solution.

I doubt that new tuners were designed and built for any STBs, the cost would 
be prohibitive. In all probability they use off-the-shelf tuners, the same 
ones available to DVB device makers.

Assuming your assertion to be correct (and I have no reason to doubt your 
word), I can't see any reason why it should be so.
