Embedded Media Display Error

Only within the last two weeks have I run across this issue but have been unable to solve the problem. When I try and embed media, although I can see the media (video) in the preview screen, when I OK it to post, I get the following error…”No Plugin Available To Display This Content”. As a result my blog post will show only title and any text but no video. I am using Google Chrome, have update my Adobe Flash and have tried media plugins for Word Press with no luck. I can’t narrow down if this is a browser, Word Press or computer issue. I can play video clips just fine when I sites such as You Tube etc…Thanks in advance for anyone help!
