I have got quite a few H.265 files and they all play on my Cyclone X4 which S805 and assume also will not do variable bitrate.

Really? Are you encoding them yourself?

Its actually a VFR (Variable Frame Rate). Not VBR. A bunch of encoders have been warning against encoding like this to prevent playback compatibility problems exactly like you have found.

Handbrake, which has been used to encode this H265 apparently foolishly defaults to VFR when encoding. Change it to a Constant Frame Rate otherwise it will be not just the Core that will have playback problems but other media players as well.
Variable Frame Rate? Well that just sounds like a recipe for disaster!! I will keep an eye out for those and steer well clear!
