I had the same issue so I installed 8.6h and still had the same issue then after 5 or 6 attempts at trying it, suddenly it came on and always comes on now, make sure you get the .exe install pack of vlc though.
I used the latest version 8.6i but i always prefer the msi version... Hmmm, i'll try the exe version but i don't understand why the exe version will work where the msi vesion fails. Let's see...
Sorry if I'm wrong, but from my p.o.v. the DreamDboxTV_V05.916.zip in the download sektion looks more like the source files, than a plug-in. If I'm wrong, then please tell how to install these files, since the read_me.txt doens't really help me.
