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.
