[QUOTE="dman_lfc, post: 1606, member: 10331"] Hi, This is going to be a bit long-winded so please bear with me... I have a widescreen TV and subsequently I use Media Portal in a 16x9 resolution. 832 x 468 to be exact. This allows me to overscan nicely. Anyway the good thing with MediaPortal is that with AVI files in this resolution, 16x9 movies play full screen without any black borders etc like they should do. Unfortunately with MPG files because the video is typically encoded at 480x576 (PAL) including borders if content is widescreen and because MP utilizes WMP then the aspect ratio does not display correctly. The various aspect ratio modes never display the content correctly and the video is squashed vertically as a result. Is there a way to crop the black borders top and bottom for MPG files that have a 16x9 or other aspect ratio's as the video content? And then zoom / stretch it to the chosen screen resolution? Here is my math on the subject.... SVCD PAL is encoded at a 480x576 resolution. All decent DVD software players know that the MPEG header should display the video at a 720x576 resolution. i.e. Stretching it horizontally by 1.5 which is how it should be displayed in any format / resolutuion. Now with my resolution (832x468) the 'normal' aspect ratio mode in MP would therefore (I assume) scale this to 585x468. Then if I changed the aspect ration to 'stretched' I would get a result of 832x468. (Squashed vertically) But if I then changed to 'zoom' I should get 832x666. MP would then crop 99pixels top and bottom from the video hopefully displaying the video as it should look on a widescreen TV. Alternatively position it as 0,-99 in this mode. Make sense or am I just babbling.... DMAN. [/QUOTE]
