Sync and video questions

I tested a 1080p 60 fps clip again, and now it worked with the menu at 2160p. I might have been wrong when I said I tested with the new version.

I will upload the logs when playing a h.264 2160p clip at 60 fps. h.265 2160p at 60 fps plays fine but h.264 clips are very slow.

I followed this guide to mount a NFS share, but I noticed that when my NAS is turned off the vero4k hangs when accessing movies. Sometimes my NAS is turned off and I want to be able to watch videos from a USB. Is this possible?
