Sample file (7.21 MB): http://www.multiupload.com/LVCIHARL72
x264vfw cannot decode this file, ffdshow-tryout can do it.
I have tried with x264vfw_34_2008bm_29021 and x264vfw.2106kMod.x86
VirtualDub say "Couldn't locate decompressor for format 'avc1 (unknown)".

Its got a strange header - some of the header information is missing/incorrect eg fccHandler is null (4 bytes of 0) instead of avc1
The directshow and ffmpeg plugins will open it though

It is rejected because it was marked as 853x480 but odd width or height are incorrect (there is no rules how to correctly interpret them) for 4:2:0 (I420/YV12). And so x264vfw simply rejects to decode video with odd width or height. |

I see a green vertical line at the right of the video when playing in MPC-HC using ffdshow-tryout and in VLC.
Maybe they add 1 pixel line to make it even.

That's what green lines at the borders usually mean yeah
Strange that avi's been a published spec for soooo long and yet they're still being so badly created (the actual files themselves, lets not even talk about production qualities, sigh)
When I saw the badly formed header, I didn't even bother checking the sizes as well
