FLVPlayback component issue

Hi all...I have created a swf file(sample.swf). In the swf file I am just using FLVPlayback component to load flv file with the default skin.

When I open this swf file(sample.swf) in flash player directly I am able to navigate the video/audio file using the seek bar. can fast forward and rewind.

But when I use the same SWF file in another SWF file the seek bar is not working... Both the swf files are local in my computer.

Following is the code I used to load the swf.
this.createEmptyMovieClip("sample",this.getNextHig hestDepth());
oivr.loadMovie("sample.swf");

Anything I am doing wrong. This is Flash8. Thanks.
