Pixel aspect ratio specifies the ratio of width to height of one pixel in an image. Frame aspect ratio describes the ratio of width to height in the frame dimensions of an image. For example, D1 NTSC has a pixel aspect ratio of 0.9 (or 0.9 width by 1.0 height). It also has a frame aspect ratio of 4:3 (or 4.0 width by 3.0 height). Some video formats output the same frame aspect ratio but use a different pixel aspect ratio. (SEE FIGURE 1 attachment)For example, some NTSC digitizers produce a 4:3 frame aspect ratio, with square pixels (1.0 pixel aspect ratio), and a resolution of 640 x 480. D1 NTSC produces the same 4:3 frame aspect ratio but uses rectangular pixels (0.9 pixel aspect ratio) and a resolution of 720 x 486. D1 pixels, which are always rectangular, are vertically oriented in systems producing NTSC video and horizontally oriented in systems producing PAL video.If you display rectangular pixels on a square-pixel monitor without alteration, images and appear distorted; for example, circles distort into ovals. However, when displayed on a broadcast monitor, the images are correct.

apparently pixel aspect ratio concerns video.

it seems the two options mentioned above are the best fixes,

the only other possibly useful bit of info i found was that you can set the pixel aspect ratio in the advanced section when creating a new photoshop file
