Hi! I'm doing some tests with a pioneer dv380 (equipped with a mediatek 1389FE) and mpeg4 aspect ratios.
Source material is 720x576 PAL DV from a Canopus ADVC100 connected to a satellite receiver, encoded to Xvid or Divx with vdub and avisynth.
Let's assume i'm encoding full 720x576 frames, without any cropping or resizing; is it correct, for reproducing the video on the standalone player, that the aspect ratio of the avi is set to 4:3 or is it better to leave it to 1:1?
With an aspect ratio of 1:1, the video looks ok on the tv (at least is fully displayed and it fills the entire screen), while with 4:3 aspect ratio, it is slightly horizontally expanded and a little part of the image goes outside of the screen (horizontally).
This is the simplest case i can think of, because things get more complicated if i start to experiment with resized or cropped resolutions, but it could be a good starting point for understanding how the chipset handles resolutions and aspect ratios.
