    MPEG2 video shows as AVC in HT4 movie details page. I think that this is a bug. Firmware is v6.3.50 on Z10 Pro.

    Those files will be Mpeg4 AVC files so the label is correct but your images do throw up another little bug - the badge is spelled wrong!

    It should say MPEG-4/AVC rather than MPGE-4/AVC:

    I am confused, the file below is AVC and also shows as MPGE-4/AVC

    MPEG is just a standard, AVC / H.264 are the codecs used within the standard. AVC is the commercial version of H.264 - the above is just parsing with MediaInfo so it depends how the metadata of the files is structured.

    Essentially though, AVC and H.264 are the same beast and are part of the MPEG-4 standard - officially AVC is MPEG-4 Part 10 I think.

    Bottom line, don't worry about it - all the above screenshots (apart from the badge spelling!) are correct.

    @Markswift2003, I understand what you are saying after reading up on Wikipedia. However, other systems including Zappiti and Plex do provide differentiation between MPEG-2 and MPEGF-4. I think that Zidoo should do this differentiation as well.

    Can you post a Media Info report from a PC of "Tears of the Sun" please.

    Thank you - will pass on..

    My guess is the logic isn't expecting HD video to be encoded in MPEG-2

    There are only a few of these that never got official release with better encode than MPEG-2. Tears of the Sun, The Omen (remake), and Shooter are the ones that I know of.

    Must admit I've never seen anything beyond SD encoded in MPEG-2.

    The Omen - what a classic!
