Videos not playing correctly in Safari
Some videos on my iMac (OS10.9.5, running Safari 9.0.2) don't play normally any more, others play fine. It's a tossup. Here's what happens- sometimes the ad promo and the video start playing at the same time, so I hear both audios, other times they begin to buffer then stop and don't play at all. I have the latest Flash player installed and active. Any ideas?
AppleTV 2, Mac OS X (10.7.5)
