    MKVs appear very grainy, with tiny artifacts displayed all over the image. The degree of graininess varies depending on which MKV I'm watching, and from what I've been able to tell, it depends on the file size of the MKV itself. MP4s display beautifully without any grain or artifacts. Also, when I use gotSent to convert a grainy MKV into an MP4, the MP4 version looks great.

    Is there a setting or something I can set to reduce this effect? What can I do?

    12 hours = definitely re-encoding being carried out. Since re-encoding always causes quality loss to a smaller or larger extent, I guess maybe the original MKVs are not fully compliant with the specs of the player. Maybe the reframe count is too high, or maybe CABAC is used or something else that the player doesn't handle too well, which re-encoding to MP4 then removes/fixes.
