Super workshop but does not without great effort on a new computer

Try me. to keep short. Delivery as usual at Amazon quickly and on time. So unpack the product and in my new notebook Win 8.1 and at the start, I then saw it, the picture completely green, only the sound was there. So the disc back out of my notebook and into the notebook from my friend Win 7 and I even have a picture. Ok what should I do so purely on the Internet and directly to Galileo Press (now newly Rheinwerk publisher) on the web site under Support. The number elected standing there (local rate) and in no time a knowledgeable staff at the other end. I have the young man briefly explained my problem and this has then told me that it is the age of the video and this was indeed pressed onto a DVD. But there is a solution he told me. After I explained the staff that is from my Windows Explorer and I do not like (for bad experience) with Firefox work we have not really come to a solution. So I downloaded it again and install Firefox and restarted on the Explorer video. After the video has started a short right started clicking with the mouse, taken out a check program again and lo and behold, the picture and sound there. Kudos to the support from Rheinwerk Verlag.
The video itself is well laid out and you can cooperate very well. It is all explained in detail. That's how I thought it would be.
