    As in official (stock) firmware I discovered that there is no way to smooth play VC1, whether interlaced or not I get stuttering image (XBMC/MX Player hardware and software). Any way to fix it?

    According to Amlogic's specification it should support the following codec:

    VC-1
    Video Codec: VC-1
    Max. Performance: 1920x1080p @ 60fps
    Audio Codec: AC3, PCM, DTS
    Container: AVI, TS, M2TS, MPEG
    Remark: Supports both progressive and interlace handling

    (In fact it doesn't say supporting the VC-1 + mkv combination. MKV supports the AVC, H.264 and WMV codec)
    Anyway, please try to provide us some test clips so that we could report to them, thanks.
    We can't guarantee it could be solved because the VC-1+mkv combination is not listed as supported by Amlogic.

    Did not know that container makes any difference! I have used tsMuxer to change *.mkv to *.m2ts and now everything is OK, thanks ;)

    Yes, container and encoding parameters make differences with Amlogic decoder. We had a discussion about this in the old forum.

    Ughhhh. Had some problems with my 8H-plus and choppy blurays. Did some googling and found this. This is disappointing that mkv containers of vc-1 won't work.

    I guess this means I will have to run vc-1 movies through handbrake, as I'd like chapter and subtitle support in the mkv format.

    Just use tsMuxer and convert it to m2ts like I did ;) In my opinion handbrake sux.

    It's possible that this is the wrong forum but...

    TsMuxer won't recognize Dolby True HD from an MKV container although it will from a Blu-Ray .iso or a Blu-Ray folder/.m2ts. What's is the best way to turn these MKV's (VC-1/Dolby True HD) back into a Blu-Ray folder/.iso? I mean, without a re-encode.
