Current frame for Spark VideoPlayer

Question

Hi all,
I've been playing with the Spark VideoPlayer but can't find a way to get the playhead's frame position.
The playhead's time is fine, but that only works with seconds and I need to get the exact timecode.
Since I know the framerate and duration from the metadata I figured I should be able to calculate the milliseconds if I know what frame the head is on...
Or does anyone know another way to get the exact timecode?
Thanks

Never mind Ryan, I got it to work with the playhead now as well. Thanks for the advise.
Now I'm only running into a problem with the actual playheadtime.
I've got a 6 seconds clip that's played in the videoplayer and stops at the last frame.
The metatdata duration value is always 6 which is correct, but the playheadtime at the last frame varies between 5.9999 and 6.1.
Most of the time it's correct and stops at 6, but it doesn't seem to be reliable.
Do you know a workaround for that as well?
Thanks
