Hmm... first jump takes 15-20 seconds. Other jumps take much less - about 5
seconds. It seems to depend on hard drive and amount of RAM. After most of the
file is cached, the speed will increase.

This is close to dd test.
dd if=video.ogv of=/dev/null
2590293+1 Datensätze ein
2590293+1 Datensätze aus
1326230110 Bytes (1,3 GB) kopiert, 15,6466 s, 84,8 MB/s

It means totem/gstreamer will read complete file to make a jump.

Beside, i have only one file which works without problems. This one has
different structure. It looks like this but is about skeleton.
