What kind of artifacts? I found one problem not related to DV but related to muxing process. When I take perfectly fine mkv or m2ts file and remuxing it with mkvtoolnix (mkv) or dv-mp4-maker (m2ts) I am getting broken macroblocks in one frame once per 20 minutes. This issue is reproducible with LG C8 and same issue on my PC, so I am guessing that something is not right with remuxing by mentioned tools. Anybody know how to fix this? I wonder which tool is better for mkv files than mkvtoolnix because original mkvs have perfectly fine video so there must be tools which are doing better job of remuxing.
btw to all which have stuttering videos: remember that LG have poor wired 100 mega lan, and blurays highest bitrate might be 120-130, so better to use USB.
