YouTube's Google Video-ization continues by using more space for the player and less space for the sidebar. YouTube changed the aspect ratio from 4:3 to 16:9, generally used for high-definition TV. Since the videos aren't yet converted to a widescreen format, you'll see an annoying
pillar box effect.
"The pillar box effect occurs in widescreen video displays when black bars (mattes or masking) are placed on the sides of the image. It becomes necessary when film or video that was not originally designed for widescreen is shown on a widescreen display, or a narrower widescreen image is displayed within a wider aspect ratio."

It make sense that they will go for a wide screen format
It looks like Youtube test the 16/9 format (on many 4/3 video too)

Only 16:9 videos should be displayed this way.

only to me this change make loss audio stream?
It's a logical progression to have videos displayed like this. More and more screens are becoming wide screen oriented especially as things move towards HD. Given time you'll be able to easily appreciate this. I have a 16:10 Laptop and a 4:3 Desktop Monitor, but when it comes time for me to replace my CRT I wouldn't get anything but a wide screen with the way things are going. In the mean time, the videos will be the same size (in non-full screen format) as they're expanding the size of the window, so thank you Google.

"Annoying pillar box effect"? Yeah...sure hampers the viewing enjoyment.../rolleyes
What's worse than the pillar box is videos that were uploaded in a letterboxed widescreen format. Now they have a thick black border all the way around.

Being mostly digital in Australia now, most of the flat panel screens in homes are widescreen and 16:9 and we are quite used to the side panels for old 4:3 presentations on it. In some cases TV stations to a nice side blocking, repeating the video content in a masked/blurred mirror or in some cases do a magnify of the pic to fill more of the space. Maybe the uploaders will get some choice when sending some 4:3 vid on how its presented in the 16:9 format on YT.

LOLOLOLOLOLOL !!!
I've noticed that since recently a lot of Youtube videos links are "no more available"
That's boring and makes me turn to Dailymotion and others video providers.
