After installing whql-win8.1-win7-catalyst-15.7.1-oct30 Catalyst software my pc lost the ability to reproduce any video neither with VLC nor with Windows Media Player. I downloaded the driver from AMD´s web page, the one specifically for APU´s with a AMD Radeon HD 6530D graphics.
My pc is running windows 7, has a APU 6 chipset with the gpu being a AMD Radeon HD 6530D graphics. For those that do not know what I am talking about the APU is an old chipset that houses in one unit the CPU and the GPU.
So go back to the 15.7.1 WHQL. You will need to upgrade your entire PC by the end of the year as Windows 7 will reach end of life on January 1st.
