Dear Praveen,
Yes, I have the same problem – I have the latest version of everything, but when I try to play, no video, only audio, and it plays very slow.
Also, the 64 Mb video limit is ridiculous, and one should not have to be a programmer to change it.
Why do you not have an option for the video to play in situ, like YouTube, rather than blacking out the rest of the screen?
Also, the WordPress options screen is very clunky – you click to change gallery setting, gallery sort, and it says “gallery not found” and you have to to back and click on “manage gallery”.
Very user-vicious program. 1/5 rating. Hopeless. Waste of time. I have just spent 10 hours just trying to upload a few videos, and it is all time down the drain.
