SeekBar works with only some FLVs

Using Macromedia Flash Pro 8:
I have this big headache creating my own video playback UI. I know there is a potential bug that will either let the SeekBar or the VolumeBar work if both happen to be on the same time line. I applied the patch and wrapped both UI components in movie clips to try and correct for this. But I'm still having this problem with some videos. I included a working example and a non working example html files. Can someone look over my files and tell me what im doing wrong?
