Some MP4's on LN46B750

I am having some troubles playing certain files on my Samsung LN46B750. They are mp4 format but I cant get them to work. I do have other mp4's that work in my library but dont know enough about this container to understand what the hicup is. Im hoping you can shed some light for me.
I did find that changing the Profile in Serviio to the Samsung A series did make these files playable but doing so I lost the ability to get any avi's that i have to play. Im not ready to dump all my avi's for mp4 at this time.
Here is the results of running the ffmpeg.exe command
C:\Program Files (x86)\Serviio\lib>ffmpeg.exe -i "F:\TV Share\Movies\Dad\Borne\b

Is there a good tool you would recommend for getting the media info? It is a movie in the HDLite format.

File looks good to me, kinda big in size ut that shouldnt matter.
ZIP - any ideas ?

I think this is due to x264 encoding options used to encode this video, I mean "b_pyramid=2" is not supported, "b_pyramid=1" could be better.
But I must confess that x264 encoding options are quite obscure...

Also, guys, for your info, in 0.6 I'm detecting profile differently. The value stored in the H264 header (as returned by MediaInfo) is not always 100% accurate - you can store whatever value there. Profile should be detected using ref_frame number with this formula (
http://en.wikipedia.org/wiki/H.264/MPEG ... _buffering)
(width*height*ref_frames)/256 ... the result defines profile using the table in the link above.
For example this file: (1280 * 544 * 8) / 256 = 21760 .. so it actually is level 4.0 file
More on this also here:

Yes, in fact, I suppose this is what is done by tools such as TsMuxer or H264LevelEditor to change the level.
Again, I prefer your method.
The profile level depends on device buffering capabilities.

Will have to see whether it works across all devices, as for some it's enough to change the header value and they (usually) play. So we need to make sure a file with profile 5.0 in header but only 4 ref frames actually plays without transcoding (keep in mind for 0.6 testing
)

So sounds like a problem with how this file was encoded...Should I re-encode? I dont want to loose any quality.
As I mentioned It works when I select the Samsung A profile in Serviio. but then none of my avi files work. Is there a way I can combine the 2 profiles (A and B) to make everything work?

With Samsung A profile selected, mp4(mov) files were transcoded into mpegts/mpeg2video/ac3, format supported by the TV.

yes but all mp4 with h264 video will be transcoded
add <Matches container="mp4" vCodec="h264" /> into following section of the "Samsung TV (B-series)" profile
- Code:
<Video targetContainer="mpegts" targetACodec="ac3" targetVCodec="mpeg2video">
<Matches container="asf" vCodec="wmv2" />
<Matches container="matroska" vCodec="mpeg2video" />
<Matches container="avi" vCodec="mjpeg" />
<Matches container="flv" />
<Matches container="mp4" vCodec="h264" />
</Video>

Thanks Illico
From the sounds of it 0.6 will handle this a bit better? Am I reading that correctly?

Yes, we hope, keep in mind, we will test this in 0.6

Probably not in the case of this file as this file is a supported profile. It might be some other setting in the encoder, e.g. the one Illico pointed out - in which case you'll have to transcode.
