"Jump to" do not work in mp4 files

"mp4" files are perfectly reproduced on several devices (PS3, Android tablets) and also on my Samsung BD-C5500 they are ok with one (important) exception: the function "jump to time" does not work: the movie simply freeze. If I remux them mkv (with --clusters-in-meta-seek option) they behave correctly, but then I have problems on PS3 and Androids.

Any hint to have "jump to" working on .mp4 files reproduced on a Samsung BD-C5500?
Thank you in advance.

Many of these .mp4 files are encoded with Handbrake (standard options: x264 rf=20 + aac).

I remuxed using the command
  Code:
ffmpeg -i video.mp4 -acodec copy -vcodec copy newvideo.mp4

but the remuxed mp4 (which is sligtly different in lenght, so something is changed) presents the same problem.

What kind of option in ffmpeg shoud I use to try to produce the same correct behaviour induced by "clusters-in-meta-seek" in muxing as mkv?

I may add that is quite strange that nobody in this forum mentioned this problem, the combination < mp4 + Samsung C reader + jumpto problem > should not be so difficult to be found...

Thanks again for your help
