There are a lot great dreams, which werent working on a windows 8 machine. Due to a resolution restriction by Microsoft.
I'am not shure, if it is the different decoder I now have, or the restrictions was removed/loosened. At least they are now working totally fine on my windows 8.1 system!
Finally I'am able to use such fine master dreams as asteroids, planetrise and other again.
Damn have I been missing those!
The decoder I use is called "ffdshow", it is freely available. I found it in this decoder pack on cnet (also only installed exactly this decoder): http://download.cnet.com/Windows-8-Codec-Pack/3000-13632_4-75871449.html
Media center is currently not installed on my machine.
