Hi, doskabouter,
Sound like you have setup you're sync wrong.
The Sync should sync both ways, but I know many experience that it only sync one way... So it all depence how you're setup is?!?!
Regarding you're second point, the Moving Picture sync... do you use Trakt?
I think I watched the movie through the videos plugin, that could be the cause.
And I don't use trakt
