I have a clip of it that plays fine. The vero playing it is networked to another vero with Gb ethernet and the clip is on a ext4 HDD on USB on that other vero, shared with nfs.
My only other datapoint is it doesn’t play nicely from a NTFS formatted SSD attached directly to the first vero with USB.
Is it a a Vero4K or 4K+? And are you using Ethernet or Wireless for Network.
89GB with a 2 hours duration is roughly 98 Mbit/s which surely would lead to buffering on the Vero4k which only has 100Mbit Ethernet.
There is a chance - definitely not a good chance, but a chance - that 5GHz WiFi might perform better. Using OS-level mounts - autofs or fstab - might squeeze a little more performance out too.
To be honest I don’t think there are so many Movies out there that scratch on the 90 Mbit mark.
So at one point you might just want to upgrade to a Vero with Gigabit.
