Questions like this come up over and over again. They should continue to be
asked, even if only to serve as gauge of the interest in Intel Graphics
support.

Interlaced Video: You will surely see a difference in video quality.
Mythfrontend does not utilize the latest deinterlacers provided by the
Intel Graphics driver. Even if it did, I am not sure that they are as good
as the Nvidia GPU deinterlacers. Kodi has a much larger developer group and
most likely uses the latest features of the Intel Graphics driver.

Progressive Video: I would think that they would be the same, but I admit
that I know little about decoding video. Maybe someone else can give better
info on this one.

Buying the i3 version with Intel HD 5500 GPU will not improve your video
quality at all.
