RE: Vista Ultimate, WMP 11 playback wrong aspect ratio (forces 16x

Tech-Archive recommends: Fix windows errors by optimizing your registry

If the content is authored with incorrect information there's nothing we can
set in Windows or in Media Player to change that.

Just to be sure, have you made sure you have the latest video drivers from
the manufacturer? We know that many of the drivers have updates to correct
issues that were being seen by customers once the OS hit the streets.

Mike,
I have this set right to 1. But I think I'm starting to track down the issue.

It seems that certain video file formats have an aspect ratio flag embedded.

The older WMP ignored this? WMP 11 does not or perhaps vista written codecs
themselves are honoring these flag(s)? Or the video driver?

And some of the files I've downloaded over the years had the flag set wrong,
but since it was ignored they played right?

That is my current working theory, I welcome any comments, corrections
and/or fixes.

Thanks,
Peter

Hi Peter,

Not sure if this will work but it's worth a try. Bring up Tools -> Options
in the media player. Select the Devices tab and when the display item
appears in the box, double click it.

Is the Pixel Aspect Ratio at anything other than 1.000? If so, please try
setting it to 1.000 and then try playing the content.

Does this help?

I have some video files that played fine on my XP SP2 Media Center 9 PC.
They should play (as most PC video files) in a 4X3 aspect ratio.

On my new Vista Ultimate machine, WMP 11, 8800 GTX video card (latest
driver) some of these videos are being stretched widescreen (16X9) messing up
the aspect ratio. Other play fine.

I've seen this behavior on both avi and mpg files.

Is there a way to stop WMP 11 from choosing to playback in an anomorphic
mode?

Does anyone know what causes it to do this?

Is there some utility I have to run on th files to flag them properly?

Thanks,
Peter
