StageVideo on android shows a black frame on the start and end of video playback

Question

When my screen starts up it goes completely black for a moment and the interface becomes unreponsive for about a second when my stagevideo player class is added to the stage. My videos are encoded using Adobe Media Encoder with the 480p android settings (vbr 2 pass). I tried cbr and that had exactly the same effect. This problem happens on both air 3.5 and air 3.4. I figure this has to be something caused by my own code because I don't see many discussions about this issue.

Using Air 3.6 on a Samsung tab 2 - Android 4.1.1
Having similar issues.
I'm trying to play a different video corrisponding with a button on the stage.
When I click the button, the video turns black, then shows the last frame of the old video then the new video starts playing.
A just want the old video to stop and have the new one play with no flashing in the middle.
This happens with both stagevideo and the fallback video object
Works fine in flash player 11 windows.
I've noticed a lot of similar type problems and some seem to be getting fixed with new Air versions.
Anyone else currently having similar issues?
