    Hi Paul

    I am also having some odd aspect ratio results on my Bravia KDL32EX600.

    I seem to think it has something to do with what FFMPEG is reporting. The following is the output from FFMPEG for one of my files:

    I am sure that in previous versions of FFMPEG the Aspect Ratio was "corrected" to for example 16:9, which is what the above comes to (approx).

    When you have a patch or a fix I would love to try it as well.

    Even though this file is in 16:9, when played on my Bravia I get black lines at the top and bottom.

    BTW, I notice that the transcoded format has changed again for the Bravias... It was M2TS, and is now MPG?

    Thanks for reporting this, Mark. We're working on the solution now.

    We did change the Sony Bravia KDL (2010 models) device profile's preferred transcoding video format from MPEG-TS to MPEG-2 to fix the audio sync issues that were occurring when transcoding video files. But, this change has introduced the aspect ratio issue for some video files. We'll fix it shortly & report back when done.

    Not as yet.

    As a workaround, for the files that have a poor aspect ratio, you can pre-transcode them to MPEG-TS instead of MPEG-2 and that should fix the aspect ratio problem. Right-click on the video in Mezzmo and click 'Pre-transcode Files'. On the Pre-transcode Files dialog, select your device and click 'Choose Formats'. On the Pre-transcode Formats dialog, choose 'mpegts' and click OK. Next select the "Pre-transcode files even if they match the device's supported formats" checkbox and click OK. Wait until the file has been full transcoded (you can monitor progress in the Transcoding pane) and then try streaming the video to your TV.

    Hi Paul

    Using MPEG-TS does fix the aspect ratio, but I am worried that the audio sync issues will be back???

    Will test a movie and see, did not have a chance this evening.

    EDIT: Did notice though that the Aspect Ratio as reported by Windows is odd:Width - 624, Height - 352, which gives 39.111:9 ??? Should be 16:9

    Cheers
    Mark

    Hi Mark,

    You are right - the audio out-of-sync issue may occur with MPEG-TS, so bear with us while we correct the MPEG-2 aspect ratio problem.

    We're still looking into it. As I mentioned in an earlier post on this thread, a workaround for the moment is to pre-transcode to MPEG-TS to not get the aspect ratio problem.

    Hi Paul

    Any news on this issue? Don't like the incorrect aspect ratio, but really do not like the lip sync issue.

    Thanks
