The codec is the same, amr narrowband. The problem is probably at
demuxer level, with sample2 and whati... files MPlayer prints a 
"stream_seek: WARNING! Can't seek to 0x5A86 ! Seek failed" message, and
when playback fails it gets an EOF. Porbably there is something in
demuxer detection that triggers the EOF.
