    I solved this issue by telling MediaPortal that the visible area is bigger than it actually is:

    Wait, my problem is that 4:3 video fills up my 16:9 screen both vertically and horozontally. And you say you fixed this problem by telling mediaportal that there is more vertical space than there actually is? How does that work?

    There has got to be a codec or something that will fix this problem properly. VLC always knows the correct aspect ratio of the video I am watching, how come it's so difficult for media portal?

    Bump.

    Sorry if I am being a jerk, but does anyone understand what my problem is? Can anyone help me fix it? Mediaportal looks like a solid enough program and i would love to use it as my front end, but if nobody can help me, then I guess I wont. Wow, that was a pretty weak threat.

    Someone in the IRC told me to buy nvidia purevideo because they said it would solve my problem. I bought it. What does it do? How do I use it? How do I utilize it's features so that it solves my problem?

    If purevideo isn't the solution, then what is? Is there a setting in mediaportal where I can tell it that I have a 16:9 tv? Then maybe it would realize that it shouldn't stretch 4:3 video all the way across. I am here begging for answers. Are my questions on specific enough? Has the issue been covered to death and you guys are tired of giving support for it and I'm just not finding the threads?

    Please help.

    Okay, cool. I'll just triple post. This problem still is not solved. Should I just write mediaportal off as another bad open-source product that just can't get their support act together and leave it at that? Is there someone besides this support forum that I can turn to?

    You are missing a rather critical piece of information, which is the exact version of Mediaportal you have installed. We had a bug in the Normal zoom a short while back (caused by none other than yours truly). If im reading the logs correct you are using 0.2.2.0 without any SVN patches, is that correct?

    Regarding the PureVideo codec not showing up, i dont really know what you are talking about as its shown clearly in this screenshot : http://farm2.static.flickr.com/1139/1243623644_4d05215ccd_o.jpg ( hint: its called NVIDIA Video Decoder :).

    As for the square calibration you shouldnt touch that(ie it should be set to 1) unless you are using a display with non-square pixels (for example a 16:9 plasma TV with a resolution of 1024x768).

    Finally, what type of file are you playing? From you logs it seems to be an AVI file which can basically mean anything (for example Xvid/DivX). Do you have this problem for all file types? Its important to note that VLC is not the best way to test, as it has its own codecs entirely independent of DirectShow.

    As to your logs, this part makes me worry a bit :
    2007-08-26 14:53:36.875000 [Info.][MPMain]: PlaneScene: crop T, B : 0, 0
    2007-08-26 14:53:36.875000 [Info.][MPMain]: PlaneScene: crop L, R : 0, 0
    2007-08-26 14:53:36.875000 [Info.][MPMain]: PlaneScene: video WxH : 1776x1000
    2007-08-26 14:53:36.875000 [Info.][MPMain]: PlaneScene: video AR : 1776:1000
    2007-08-26 14:53:36.875000 [Info.][MPMain]: PlaneScene: screen WxH : 1708x978
    2007-08-26 14:53:36.875000 [Info.][MPMain]: PlaneScene: AR type : Normal
    2007-08-26 14:53:36.875000 [Info.][MPMain]: PlaneScene: PixelRatio : 0.9
    2007-08-26 14:53:36.875000 [Info.][MPMain]: PlaneScene: src : (0,0)-(1776,1000)
    2007-08-26 14:53:36.875000 [Info.][MPMain]: PlaneScene: dst : (27,56)-(1735,922)

    First off, the video appears to already be 16:9 (1776x1000), so either the codec used for playback already upscaled it (possibly incorrectly) or it is indeed a 16:9 source. The second thing is that there seems to be an error in the computation of the dst rectangle (27,56)-(1735,922) as the screen is reported as 1708x978. You might want to try a more recent version of MediaPortal.

    As to our 'support act', if you have a need for professional support you might want to buy a commercial product like Windows MCE. Please recall that the time i have just taken to respond here goes directly from my spare time.
