I found a bug in the current version of the firmware (version 1024) for the Samsung TV UN55D8000. I just wanted to let people be aware of the issue.
The issue is that the app flashes black when a video attempts to loop.
I have the stageVideo seek to the start to its 0 point when the netstream reports that the video has reached its end.
When the video loops, the entire app flashes to a black screen for a split second.
This is NOT a problem on the Broadcom developer box or on TiVo devices - just the above mentioned Samsung TV. Therefore, I assume this is a Samsung bug.
