I have just ripped my complete collection of Doctor Who blu-rays (Series 5-9) using MakeMKV and while some files play back okay, I am getting persistently choppy playback watching many of the episodes. The audio is fine, but the picture keeps freezing and skipping. Sometimes it will play fine for a while, then the choppiness returns.
Watching other 1080p material, e.g. movies ripped from blu-rays, this has never been a problem before.
I am streaming from a WDMyCloud NAS via Ethernet to a 4th gen Apple TV. Connecting via UPnP or SMB hasn’t made a difference, nor has changing the frame rate in the Apple TV settings.
Any other ideas?
