Issues 2&3 also resolved!

After reading somewhere here about a warning using air mice, I decided to reinvestigate the other 2 issues.
It seems that the box has some strange quirks using an air mouse.
Beware there may be other quirks!
Earlier I had tried to use the original remote when the video had started, it did the same thing as the air mouse, so I did not think this was the problem.
After a revisit on this issue, I tried using the
original remote to navigate and start the video and it all
worked normal.
If I use the air mouse to navigate and start the video, the problem is there, even if you use the original remote to bring up the menu while playing.
I have tried
3 air mouses and they all have the same result.
It's like a out of sync issue, maybe if I used the directional cursor on the air mouse it would work, but kinda defeats the purpose.
Great forum (futeko), thanks to all for the suggestions.
