AFAIK, the specs for the TT designs have never been published either,
and the drivers you have now are the result of guessing and reverse
engineering. I don't see why this shouldn't be repeated for more
up-to-date designs than the old TT ones...
because for example that hassle about not beeing able to predict
if the TT cards shipped next quarter will work, or will need some weeks until they can be used, sad but true Joe Average will go for the 100% chance, and not save 100 bucks on the dvb card he has to spend on gfx and a new cpu or a second pc.

True - but soembody actually has to _do_ this ;-)
Apparently the interest in this isn't high enough, yet...
Maybe the incentives just aren't high enough - why bother reverse
engineering a design that's technically no improvement over the TT ones?
Now if there was a card that was actually a technical advance (e.g. a
DVB-S2 card, or a hybrid DVB-C/T card, or a card with a better suited PCI
bridge with a deep FIFO, or a card with a much quicker sync'ing
demodulator), I'm sure someone would get into reverse engineering it...

Exactly, that's the point.

IIRC some recent budget cards also require closed-source firmware,
which has to be taken from the windows driver.
This is a step in the wrong direction.
Get real. These cards are again Technotrend cards. Or do you know
another design which is using the TDA10045 demod?
well, that does not counter the argument, its still not better.


There is no advantage except that these cards are really cheap.
?!? sorry, I don't understand you. They do their job and are cheap,
isn't this advantage enough?
well you save 100€, but loose one pc, or at least quite some resources,
esp. if you actually do what you promote: fancy osd, p-i-p, osd overlays, mpeg4, HDTV, ip streaming.

b.t.w. i like the concept/output of the (linux) dbox-2, no wonder they don't care about vdr.

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,

What?? They have a better OSD? I thought they don't have an OSD at all
(let a lone a TV out)?!


they don't
force you to do anything on the card what can get done much easier and
better on the host processor.


Why should we waste out time with cards which are not better than the
old ones?
open your eyes. they are. Simplicity and reliability is a significant
improvement in my eyes.
well are the simpler to install ?
they are more reliable in pure reception, but does this realy reduce the total number or errors (inluding the decoder, osd and
a like) ?


Holger, please realize that we are talking about FULL FEATURED cards here!
IMHO a DVB card that is really worth using (as primary card, of course),
must provide TV out (which implies MPEG decoding and OSD). Of course
there may be people (like yourself) with different opinions, who are free to
use VDR with the necessary plugins to do the output via graphics adapters
and soundcards. I for myself prefer the way the FF DVB cards do it, even at
the cost of limited OSD capabilities. I don't need all that "eye candy"
stuff that's often talked about. What counts most is functionality, not beauty.
After all, what I want to use this for is watching TV, recording stuff and
replaying it. Whether or not the OSD menus have thousands of colors, a
"graphical" interface (I never understood why some people are so afraid of texts)
or fancy background images doesn't matter. The really important functions
are somewhere else.

Yes thats the point, for something like tv, no primers are wanted, solutions are prefered.
