i see that MP4 video is supported, however i just setup my WD HD TV Plus and picked a mp4 to play, it said its not supported.
Did i miss something?
Brand new user here…so be gentle. Search function wasnt very helpful…
Welcome to the forums.
While the MP4 container is supported, a whole lot of codecs can be in that container which are NOT supported. Post the Mediainfo information about the file that won’t play and we can be of more help.
im sorry im a tad new, where exactly do i get that info?
i know the audio codec is AAC, which im guessing is the problem since its apple?
i have a feeling im going to need to convert this to a different audio codec?
thanks for the quick post, wow…
AAC isn’t a problem per se (actually, it’s good) but you don’t want 5.1 AAC (which isn’t supported by most all devices).
MediaInfo is a freeware program (I think it comes with the WD on the CD). Running it will tell you the properties of the file (which you can post here).

Yeah, it’s that second channel of audio (the AAC specs actually don’t allow for 6 channels but it can be forced. Most devices don’t support it, though).
Just remove it (you can do it with a wide variety of tools, like mkvmerge) and you should be fine.
thanks, im guessing i remove the ID3 part and remuxing to a new output file?
Yeah, with mkvmerge all you have to do is uncheck that audio track and remux to a new file (shouldn’t take more than a few minutes).
Oh, but be careful – you do NOT want to use the latest mkvmerge (unless you turn off “header compression” in the audio track options). Best bet is to use the 4.0.0 or earlier versions.
ohh, i just used the 4.1.1…how do i disable header compression in the new one?
cant seem to find a earlier version of mkvmerge…it works, but im wondering if i did something wrong…im only checking using TV’s sound
Well, if it works then you’re okay – however, in the future you should get the older version:
http://www.bunkus.org/videotools/mkvtoolnix/win32/mkvtoolnix-unicode-4.0.0-setup.exe
I think to turn off the compression you highlight the audio track and go to track options, but since I don’t have (and never will) that version I’m not positive.
thank you very much for your help…everything is working great.
