Although this is an old thread, I am also having the same problem.

I have an xvid file with the wrong aspect ratio so I try to change the "display ratio" in Mpeg4 Modifier, but when I view the resulting xvid, it's still the same.

Please help

All MPEG4Modifier changes is a flag. If the decoder recognises the flag, then you get the AR set, if not then you don't.

DivX, XviD, FFDShow, mplayer, VLC all should recognise and resize correctly. So the question is what are you using to decode?
DivX would need to be recent. Older versions of XviD contain a bug where it doesn't resize if the file has bframes that aren't packed and FFDShow requires that you have overlay and allow format changes enabled, although I believe this is fixed in newer versions.

Sorry celtic_d not sure what you mean by the question.

I have installed the latest XviD codec. and use wmplayer to watch the XviD.

Having XviD installed, doesn't mean that it is used to decode. dshow works on a priority system. The filter with the highest merit is used.

Also define "latest XviD codec". Possible you mean 1.0.3. That isn't the latest and is effected by the bug that I mentioned earlier. You need a recent 1.1.x or 1.2.x build. These also fix a bug where the playback and encoding AR info was stored in the same registry key. With earlier builds if your last encode was set to 16:9, then playback was set to 16:9 instead of auto.
