BD-E8500N PIP bad functionality

[mesersmith]

I must ask you if you have the same problem like I do, or I miss something in my operate this machine.

I am o channel 1 and the commercials begin. I put channel 1 in pip window and on the main screen I begin to look on another channels.
When commercials ends, I need to bring the pip window to the entire screen.
I did not found this function on the remote or in the manual.

Now, I must memorize the number of channel that I watch, I put it in pip window, and when I need to come back to it, I tape its number o remote.
You know another way to do this?

Thanks for your answer.

Those who have tv screens with pip function, do you have the same problems?
