Serviio

Hi, on my BD Samsung HT-F4500 the .mkw files don't working...
Do you have an idea of what I need to verify / settings?

Thanks

MKV or MKW? MKW (an audio format I hadn't heard of before) is a not supported by Serviio.

If it is MKV file, try changing profiles. What profile are you using on the device?
