That doesn't sound right.

I stream video from a NAS box all the time without issues, on 100baseT.

What is the bit-rate and size of the video files?

As far as "disk based disk cache" goes, I don't see the point.  Even if
you could somehow do that, video is streaming, so the nature of a cache would
basically work against you.

It would be easier and faster to just copy whatever you want to watch and
watch it.
