Why can't I watch an MP4 movie file?

I have the latest ffdshow codec which apparently decodes MP4 media files, but when I try to play it in Windows Media Player there is no video and the sound is messed up

Can´t say why, but would suggest trying a couple of other players:
VLC (which you should have anyway) and GOM (this seems to be able to play anything…even damaged files).

What are VLC and GOM and where can I find them?

VLC will PLAY the clip, but I want to use Nero Vision Express to burn it to DVD. I need an MP4 codec for this. Does anyone know where I can get one?

Are you trying to convert the mp4 into dvd video? It might help to know the codec used in the mp4. It could be xvid or divx or H264. You can examine the file with MediaInfo and find out what is used in it. MediaInfo is free to download and use. http://mediainfo.sourceforge.net/en

This is the information I found on the file:

Format : MPEG-4
Format profile : Base Media
Codec ID : isom
File size : 1.47 GiB
Duration : 2h 2mn
Overall bit rate : 1 721 Kbps

Hmm, that didn’t help much. Try the Tree view in MediaInfo and see if there is more. Really looking for the video and audio codecs.

It’s easier to post a screen shot than write it all down lol. Not sure if you can blow it up to make it easier to read or not though

Ok, what you have there is AVC video codec which in this case was using the X264 encoder (the free branch of H264). And you have AAC audio. All of which is fine for an mp4 container.

When you say you have the latest ffdshow, are you using this one? http://sourceforge.net/projects/ffdshow-tryout/files/

Which version of Nero are you using? The latest should also support these codecs. If you are trying to convert to a dvd video, and cannot get Nero to work, I suggest trying AVStoDVD: http://www.videohelp.com/tools/AVStoDVD
Make sure to set output to your area’s standards, which in your case would be PAL.

And by the way, simple copy and paste works best for log files. You can add Code tags to them to make them more readable on the forum.
