mplayer can't rewind movie

I have a mp4 file. I opened it with mplayer. It works but when I rewind the movie the picture goes wrong. When scene changes all gets cleared. Unless I rewind, it works ok.

I think the file is wrong - compression is to great or sth similar. How can I improve it? Can I alter the file somehow to dispose the problem?

PS. if the problem has already occured somewhere, redirect me. I didn't know how to call this problem so I ask here.

Do you know what's inside the file? What codec is used for the video and audio? If I remember correctly MP4 is merely a 'wrapper' around the contents that tells the player what to expect.

I have had similar issued with regard to rewinding movies when the file in question was a Windows Media Video.

I found this in mplayer output:

Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
Selected video codec: [ffh264] vfm: ffmpeg (FFmpeg H.264)
Opening audio decoder: [faad] AAC (MPEG2/4 Advanced Audio Coding)
FAAD: compressed input bitrate missing, assuming 128kbit/s!
AUDIO: 48000 Hz, 2 ch, s16le, 128.0 kbit/8.33% (ratio: 16000->192000)
Selected audio codec: [faad] afm: faad (FAAD AAC (MPEG-2/MPEG-4 Audio))
shortly speaking:
video codec: [ffh264] vfm: ffmpeg (FFmpeg H.264)
audio codec: [faad] afm: faad (FAAD AAC (MPEG-2/MPEG-4 Audio))

If anything else I need to know about this file, tell me.
