  1. I'm new at this so just wanted to clarify a few things
    Firstly, I have just bought a Bush ELED42240FHDCNTD3D 3D TV and decided to drag some video files onto a USB drive to play through the TV in SBS format. I put the drive in, adjusted the setting for SBS and got the picture fantastic. What I don't understand is why I get no sound? Also the video file seems to ghost instead of good 3d, is there any way around that?

    Any help would be greatly appreciated, and some knowledge of how to go about viewing 3d films would be great as it is what I bought the TV for

    Thanks in Advance,

    Heather

    My guess it the TV can't decode the audio in the media file. Obtain a report listing your media file audio's characteristics (using MediaInfoXP or something else reliable) and compare that against what your TV allows for that type of media file. (The information you need should be in the manual supplied with the TV).

  3. Wow that was a fast response! Thankyou so much
    Firstly, the file was .mkv which my TV accepts. But the audio file is listed as DTS which it doesn't.

    So my question now is; what can I use to stop the ghosting, and to convert to an audio file it uses?
    The ones it can use from a USB for .mkv files are : mpeg 1/2 layer 1/2/3, AAC/HEAAC, AAC/EAC3 and LPCM. Trust me when I say that i'm a stranger to some of those formats :/

    We aren't clear what you actually mean when you say GHOST. Do you mean something like this:http://en.wikipedia.org/wiki/Ghosting_%28television%29#mediaviewer/File:TV_ghosting_interference.jpg?
    Ghosting can be captured that way with bad analog equipment, or it can result from interlacing artifacts. Sometimes motion blur is mistaken for ghosting.
    And sometimes, incorrect 3D processing of the 2 images looks like ghosting. In fact, sometimes even CORRECT processing & display of 3D produces ghosting (via crosstalk). Check your manual (~pg 40) to see what formats are compatible or not. If you are unsure, run the file through Mediainfo and post a copy of the detailed (advanced) text readout.

    Well, for the audio part, it's clear that your TV doesn't support DTS audio. You'll have to re-encode the audio to a different (more compatible) format.

    I seem to be one step behind in the posting today...

    You'll need to:
    1. Demux (extract) the audio to a raw DTS track.
    2. Decode the DTS to LPCM and either leave as-is or re-encode to ?aac?
    3. Remux you new audio with your original video (but without your original audio).

    There are tools for all this on this site.

  7. Yes, like that but only towards the 3d background. Apparently, 1080p Frame Compatible through MBV is supported by the TV. How do I do a detailed mediainfo scan? That's all I get when I run it?

    Thanks for helping Scott and usually_quiet

    Can you point me to what I need for remuxing? As I said , this will be the first time I've had to do something like this :/
    Also are there instructions on how to use the apps?

    Well, that was detailed enough.

    It's hard to tell from the manual: is your TV an Active 3D (LCS) type or a Passive 3D (Cir. Polarized FPR) type? Active type uses glasses that must be turned on & off and use a battery - is this your kind?

    As mentioned, ghosting can be due to inaccuracies in the extinction of the crosstalk component (glasses lenses aren't doing a 100% job in showing ONLY their desired eye-view). We'd need to know more about your system - maybe it's the TV, maybe the glasses, maybe your material is just VERY deep parallax and VERY high contrast (which exacerbates ghosting), maybe a combo of the 3.
