Yes, it seems mplayer can play test.MTS correctly, but, as this topic
title said, I can't get correct ID_LENGTH through mplayer.

"mplayer test.MTS -demuxer mpegts -identify -ao null -vo null -frames
0" output "ID_LENGTH=0.00",
"mplayer test.MTS -demuxer lavf -identify -ao null -vo null -frames 0"
output "ID_LENGTH=6.72", so, I think there is something wrong when
mplayer handle this kind of video file.

Isn't it?
