I've got FLV file, that is treated badly with built-in FLV splitter.
When i switch KMP to use Gabest splitter - bug disappears.
Sample file: http://www.mediafire.com/?eyx1im3n1sqjv

Tested on: KMP 1439 / ffdshow-tryout recent / Vista x86 / Q6600
and on: KMP 1438 / ffdshow-tryout recent / Win7 x64 / Phenom 710
Trouble: when you scroll inside the video, to some position ahead or back, KMP freezes for 10-30 seconds before position is adjusted and playback is continued. That, providing built-in FLV splitter used.
This includes just opening the file in KMP, providing KMP is set to remember quit position of fie and to continue from that remembered timestamp.
