as already some gored with their FullHD video in 4/8K - just re-convert .mve to avi using a simple divx/xvid codec with a size of 1280/960x720, in order to be pleasant to the eye, there is no point in doing higher than this size.
I've never seen such problems.
This is probably some local incompatibility issue of yours with HRP. Many people have noticed blue curbs due to HRP.
Whether there are such problems without HRP?
