I got 2 QuAD LNB's - connected using a DISCeQ on each cable to each 
input on it's own Cable.

I have 32"" LCD with VGA input(1024x768).

VGA Cable.

Yesterday when there was Championsleauge -  the players looks very very 
unsharp and was very hard to read the numbers on the players, but the 
commercial was way better looking. TO start with - it's not lagging or 
anything - just very unsharp contra using my Dreambox.

None of the TV-recordings or anything are lacking, and a DVD played both 
from DVD-drive or from BE - looks very nice without complaining. SO My 
guess is - that its nothing wrong with the networking part.

At the HVR-4000 I cannot get the subtitles from the moviechannels to 
run, but on those channels where they ar esent along with the signal - 
they're OK  - but on those where I should be able to chose the 
subtitles, There's no options for chosin subtitles.

And My frontends have onboard Soundcards ( Running COAX til my Surround 
reciever - But can only get output when choosing 2CH instead of AC3  
which I thinks its strange - but need to play arounds a little bit more. 
Did try to play with the MPEG settings - but didn't think/see it as much 
different - Seen from my eyes, when playing the football match!

But after work - I'll give yet another shot again!

OK - That was not the meaning to misguide people.
