Black bars on sides of MTS files
How come when I drop MTS files onto my SONY Vegas 10 timeline I get black bars on the sides of the preview window? If I look at the frame size it doesn’t show any. They disappear if I turn off the Maintain Aspect Ratio setting. This is 1920×1080 frame size I’m working with. I don’t get that with other types of video. And when I render the video down to mpg to put on to DVD’s the small black bars remain unless again, I turn off the Aspect so the program stretches the image a bit. Just don’t understand.

What you need to find out is what the Pixel Aspect Ratio (PAR) is for that MTS Media and Match your Project Settings to the same as the PAR of your Media.
If I put a Square, 1.00 PAR Media, into a 1.4568 PAR Project I get the same as you, those Black bars on each side.
So, and to test this, put a sample of your MTS media into a New Project. Do you get those black bars? If not then your Project PAR is the same as your Media. If you DO get those black bars, locate the Icon on the very top right “Match Media Settings” and click. When the next Menu appears, navigate to that MTS Media you have placed on your test timeline, and select Open. Once you return to your Project Settings the PAR will reflect/show what the PAR is and will setup your project correctly and you shouldn’t get those Black Side Bars.
What we need to take on board is that the Aspect Ratio (16×9 or 1920×1080) does not directly relate to this Pixel Aspect Ratio. The PAR is the actual “shaped” ratio of each and every Pixel. My HD 1920×1080 has a a PAR of 1.00 or 1:1. While my HDV is 1.333 or 1.333:1 – each pixel is wider than it is tall.
