Problem with Rewrapping and fast forward

Hi @ all,
1st of all serviio is the best!
But
In moment i have to rewrapping .flv-files for my Philips BDP7600.
It works in generall well, but the fast forward will only work with 2times-speed and a time jump also not possible.
Normally i can fast forward with 32x.
Is there any possibility to get the normal behaviour?
For information here are my profiles.xml lines
<Video targetContainer="mpegts">
<Matches container="flv"/>
<Matches container="matroska"/>
</Video>
Thanks a lot for all help.
