My dad just got a Roku Express. All the videos he plays on Roku Media Player play too fast. It's like double the speed. My sons TV also uses a Roku Express and videos play fine.
He's connected to a Serviio server. His TV is a Samsung A450 Series.
I've tried changing the resolution within Roku. Doesn't help.
All the other TV can play the Serviio videos fine.
Any idea why this is happening?
