Here's what I found ... I had to install Quicktime 7 and use iwork 09' (using them in mavericks) ... Using those two and opening projects in those two, works the way it should be.
There's an issue with the NEW Quicktime ... Even if you open and older .mov, it still won't let you control your keynote prsentation.
If you want to control your keynote presentation ( like the way it was), then search Quicktime 7 and use iwork 09'.
Here's what I don't understand ... Being able to convert any keynote presentation to a .mov is a major deal for videos. When they release the new stuff, doesn't anybody actually look at it first? ... Ya' know, to see if it actually works before releasing it? I get that a few things can slip by, but c'mon, major funtions ???
ALSO ........ When exporting the new keynote ( version 6). You can't export to a .mov ... It says quicktime, but it saves to a mv4.
I can see adding value, but stop taking away value !!!!!!!!!
