RE: Some of my mp4 movies will not play
For troublesome files, post a mediainfo report:
http://mediainfo.sf.net

MP4 is a container, it could host codecs/formats that are not supported, and sometimes they are disguised .flv containers.
Another possibility is that the file is corrupt or partial.

But that's just speculation until we know what's really inside that MP4.

RE: Some of my mp4 movies will not play
Codec ID: mp42 ?

I'm not sure, but I don't that format is supported. Quering Google it appears to be a Microsoft codec.
Taking a guess here, but if you open any other of your working MP4 files (that plays OK) you will probably not find mp42.

If my theory is correct you'd need to re-encode these fiies if you want to play them on the NMT.

I have the audioconverter tool and tried to use it but it seems it only works on mkv container files. Is there a similar tool avail for the mp4 container?

RE: Some of my mp4 movies will not play
You have not posted the top part of the mediainfo output.

MKV is generally better supported than mp4. Things like subtitles support, meus, chapters, etc. mp4 has Apple undertones as well Big Grin

Someone suggested a software tool to get from mp4 to MKV ina thread I read recently, can't remember it but try doom9 for it.

RE: Some of my mp4 movies will not play
Well..following Chri's advice I converted the mp4 wrapper to MKV and voila it plays just fine.

I used MKVmerge and this tutorial http://www.ehow.com/how_5879049_convert-mp4-mkv.html

RE: Some of my mp4 movies will not play
Glad its working.

It doesn't look to good quality wise. More for phones than TV with its bitrate/size v's its resolution.

Make sure you update MKVMerge to the latest version, think its v.4.6.0.

Here's a Guide plus links and pictures from the WIKI:-

RE: Some of my mp4 movies will not play
Not sure what you are referring to. The tutorial I linked has a link to the latest version of mkvmerge and it worked fast and the quality is spot on.

Thanks again for pushing me from mp4. Guess I never realized how crappy a container it is.
