I did not find what formats your Samsung HT-F6550W supports. I just saw that it supports 5.1. It may not support DTS-HD and Dolby True HD
Does your Samsung HT-F6550W have display that posts the audio format?
Have you configured windows with your speaker set up by right clicking the speaker symbol in the lower right windows task bar, selecting your playback device, Samsung HT-F6550W. and then configuring your playback device in windows?
I think that if you use MPC-HC for playback you can set the program up to do the decoding. However, I use an AVR so I am not sure. But I am not sure you can then bypass the Samsung HT-F6550W.
