There are no problems with vu+, only with dreambox. There are many who have tried vu+ and the sound is great. Also, the problem is only with satellite, not with cable.
I have also the same problem, how can we help you to help us to get rid of this annoying sound issue? The thing is that the sound is really crap on HD channels like TV3HD and TV4HD. Also noticed that it is the left channel which causes "wobble" when the sound has more bass that usual, like when playing music and commercials. Have tested with rca and optical, no difference.
OK, now I found out that there are many others with same problem. These seems to be a issue with the sound from a few big swedish TV channels, TV3HD and TV4HD, also problem found with other HD channels.
