    Default No Transport Controls with Some DVD ISOs

    With some of my ISOs, pressing fast forward skips to the next title instead of actually fast forwarding (Sony BDP).

    As an experiment, I set a title in question to pre-transcode to M2TS... voila, I now had working fast forward and rewind.

    Any ideas as to why this is happening?

    I am guessing that your Sony player can't do FF/RW for VOBs. This is one of the reasons I rip all of my Blu-Ray and regulat DVDs into the m2ts format. I realize it won't help you for normal DVDs if you are using ISOs.

    Jeff may be right - it may be a limitation of your Sony BDP, or it may be that Mezzmo is transcoding your DVD ISO video on-the-fly since it has a codec (DTS?) not supported by your BDP player. When transcoding on-the-fly, many devices don't like FF/REW. Right-click on the DVD video in Mezzmo and click 'Get FFmpeg Information. Post that information here.

    As another experiment, I chose the "Use Original File" (no transcoding) option, and the file played fine, but again with no FF/REW.

    With some of my DVD ISOs, FF/REW work.

    Thanks for the FFmpeg information. The file looks fine for your Sony BDP to play natively, so Jeff may be right - it may be a limitation of your Sony BDP when playing VOB/MPEG-2 files. To be absolutely sure, turn on logging (see http://forum.conceiva.com/showthread...nostic-logging) and restart your Mezzmo server. Reproduce the FF/REW problem on your Sony BDP and then stop your Mezzmo server and exit Mezzmo. Zip up all the logs and email them to us at support [at] conceiva [dot] com.

    [EDIT]

    After even more research and testing, I've decided to use ByteCopy's "Directly Copy" option for DVDs and BDs (instead of making ISOs):

    • FF/REW are very fast with a .vob created from a DVD (I expect the same from .m2ts from a BD).
    • Copying this way is much faster than using the MKV option (no need to convert to H.264).
    • No transcoding is required during playback.

    Thanks for sending the logs. We'll analyse them and respond back shortly.

    Regarding your further testing, I guess you may have found a good format that your Sony BDP can play well.
