MKV stopped working on UN46D8000 after 1024 update

Hi,

I am on Serviiio 6.0.1. After Xmas vacation I updated my Samsung firmware to 1004. It also downloaded the latest SmartHub update. After this update all of my MKVs stopped working. When trying to play it says "Unsupported file format". Anybody else experiencing this problem? Is this something that is caused (or can be solved) by Serviio?

Thank

make sure the TV hasn't changed its IP and the right profile is still assigned to it.

Thanks for your advice. That was it. After the update the profile has somehow reset to Generic DNLA device. Once I changed it back to Samsung specific profile, all is well now.
