Dxtory Codec and TMPGEnc VMW5 problems

[Magogan]

Hi,

not sure who is responsible for it, but I have decoding issues with TMPGEnc Video Mastering Works 5 when I use the Dxtory Codec (4:2:0, compressed). It sometimes produces pictures with the lower part being garbage, see attachment. What can I do about it, apart from using a different codec or editing program?
