Dentro das tags (ajuste os valores de acordo):
<usetimeseeking>true</usetimeseeking> <!-- Whether to use time based or percentage based seeking. -->
<timeseekforward>30</timeseekforward> <!-- Time to seek forward in seconds when doing a short seek. Defaults to 30. -->
<timeseekbackward>-10</timeseekbackward> <!-- Time to seek backward in seconds when doing a short seek. Defaults to -30. -->
<timeseekforwardbig>300</timeseekforwardbig> <!-- Time to seek forward in seconds when doing a long seek. Defaults to 600 (10 minutes). -->
<timeseekbackwardbig>-300</timeseekbackwardbig> <!-- Time to seek backward in seconds when doing a long seek. Defaults to -600 (10 minutes). -->
