Reproduction steps:
1. Open the attached project "unity-video-tests" and load Scene "SampleScene"
2. Open "Scripts/Seeking.cs" and comment out "#define AVPLAYER" in line 2
3. Enter Play Mode
4. Click the "Download Video" Button at the top of the Game View
5. Click the "Prepare Video" Button at the top of the Game View
6. Click the "Seek" Button at the top of the Game View
7. Observe the time value in the top left and the clockTime value (named "Time") in the middle bottom of the Game View

Expected result: setting VideoPlayer.time to a specific value results in VideoPlayer.clockTime changing to that value
Actual result: setting VideoPlayer.time to a specific value results in VideoPlayer.clockTime being ~0.5 of a frame's duration smaller than VideoPlayer.time
