1.Launched the video, the normal state.

View full screen, then turned again and got ...

This is when viewed video youtube.

2. Now for the video uploaded to the site itself. After decoding the output I get a thumbnail playback.

both in the folded and unfolded state.
3. control panel is loaded at once by pressing play, and about 5-10 seconds or not start at all.

I would like to see the setting the aspect ratio of 16: 9 and 4: 3 automatically. As well as a choice of quality. At least for those videos that are loaded with YouTube.
Of minor bugs discovered that the player does not store the sound settings, then reload the page, the sound again at 100%.
And finally ...

It appeared after I clicked on the video to youtube added. But not always, but 5 times 2 precisely.
And by the way after that strongly slows down the site.

Hi, Серёга.

We are aware of that issue - was already reported.
I hope that our developers will fix it soon.
