None... the files are stored on the MacBook Pro - I can see them in Finder - but iTunes does not play them... anyone else seeing this?
Odd... I even went so far as to re-install Yosemite via the Public Beta... Still same issue within iTunes... I'll give QuickTime a go...I can play it via QuickTime from the Finder. But not within iTunes.
For me, the issue didn't appear until Beta4 with iTunes 12... Then I reinstalled with the Public Beta... issue still remains. I did send it in via Feedback Assistant... perhaps today will be release day for an update that fixes everything... one can hope.It's not iTunes 12, at least for me. It's Yosemite Public Beta. iTunes will play standard def movies but not HD, not purchased ones from iTunes anyway. No error codes. HD movies will actually play as in the counter/timeline is counting/moving but no picture and no audio. It's the same in iTunes 12 as I was using it before I reinstalled Yosemite and am now using iTunes 11.2. Must be HDCP issue as I never had this problem with Mavericks on this machine/monitor and no problems on my main OS X machine running Mavericks. We'll see what future betas have in store and realizing that this is an early public beta I understand there will be issues.
