How to get buffer bar to show up?..Please advise what to do.

I have a graphic that opens when channel is picked. Then it goes black and then the video begins playing.

How can I get a buffer to show the video is loading instead of the black screen before the video plays?

The videos are a list in the xml that play in order.

I posted another note in the forum about how to get the main graphic to stay on the screen while video loads but nothing in that code I posted is working. So I have it messed up most likely.

So if I can at least get a buffer bar to show then that should work so the viewer knows the channel is loading and I can get this channel approved this week.

Thank you if you can help at all.
