I have a problem with the dm500.
Since I got this machine (2 days ago) the sound has a delay.
I changed a couple of images and the problem remains exactly the same.
The picture is good without freez but the sound comes out with a delay like a nearly dead person try to speak.

Please can you help me or I must take this receiver back to the shop.

i have a receiver with the same problem, did you find out bout your problem yet?
i also emailed dreambox several times they never respnded back now that receiver its almost a year old
