Video Aspect Ratio

I have had issues with video aspect ratio, openlp seems to ignore it and just resize it to the shape of the screen, which means sometimes I need to reencode video to have black bars to get it to look right. And when that gets fixed it I would like to note that anamorphic video might be a problem because the pixels are not square and I do not really want it to be half fixed but not completly fixed. iH, Thanks.
