Hello,
please dont hurt me about this topic but I have a big problem in understanding. I try to build an autocrop addonon for dvdx to solve my problems in understanding aspect ratio. Ok what I do:
I have different PAL Movies. I try to detect which width and height the movie has, and get the aspect ratio from the Ifo. In case of this, PAL is everytime 720x576 pixels. Ok thats good. I put in DVDx the picturesize of 720*576 for 4:3 Movies and 720*400 for 16:9 Movies.
Now I encode this movies to have some testmaterial. But then, after I had encoded the movies, I play my encoded movie with a aviplayer and the dvd with WinDVD to check if the frames/Pictures are equal.
NOW THE PROBLEM OCCURS. On WinDVD some Movies, like "Saving Private Ryan", "The Shawshank Redemption" and a german movie "Sieben Monde" are shown in WnDVD in a different size. Means the height of the movies are more than my encodes movie. And the faces are strechted more than the ones in my movie.
So, I take the MediaPlayer and start Playback of the DVD. And in the MEdiaPlayer, the DVD is shown extactly in the same size I encoded my Movie.
Ok, my last test was, to check the data from ifo with smartripper and vstrip. Vstrip gaves me the exact data I analyse: 16:9 and 720*576. But Smartripper says me, that the movies has a Aspect Ratio of 4:3.
So my question is: Is there a Bug in WinDVD and Smartripper, so Smartripper gets the wrong data and WinDVD shows the movies incorrect or do I a fault and the WindowsMediaPlayer has the same bug that I do?
