Get real. These cards are again Technotrend cards. Or do you know 
another design which is using the TDA10045 demod?

?!? sorry, I don't understand you. They do their job and are cheap, 
isn't this advantage enough?

You accept silently all the limitations of the av711x: a OSD that is far 
from what you expect for a modern STB (the OSD is not even able to 
display 8bit DVB subtitles correctly), no way to pass a high-bandwidth 
stream to the host and process it there, no way to decode HDTV or even 
MPEG4 sources. Their cheap alternatives provide you all this, they don't 
force you to do anything on the card what can get done much easier and 
better on the host processor.

open your eyes. they are. Simplicity and reliability is a significant 
improvement in my eyes.
