AVI 2.0 XVID with DivX header can't be zoomed?

[emphatic2]

I'm currently playing back some .avi's on my 16:9 TV using S-VHS out from my Avi Videocard.
Everything works perfect, just one little snag: Some XVID files can't use the "zoom/aspect ratio" function.

I've checked them with GSpot and the major differences are:

"Zoomable":
Packed bitstream: No | Container: Avi 1.0 | User data: [ISFT] transcode-0.6.14, [USER] XviD0037

"No zoom":
Packed bitstream: Yes | Container: Avi 2.0 | User data: [ISFT] VirtualDub, [USER] DivX999b000p, [USER] XviD0038


I'm playing back these files with (I'm kinda guessing here, since Media Center doesn't have many settings): the ffdshow codec. I have tried unpacking them using MPEG4 Modifer from http://www.moitah.net/ but that didn't matter.

I've also tried converting the container from AVI 2.0 -> AVI 1.0 (Using VirtualDub MP3) but that didn't work either.

If someone knows why the zoom doesn't work for some XVID files, please help!
