Works for me!
I just love articles like this and it did get me started with scripting for Avisynth. I had avisynt installed because I had used it to load a real-player video into VirtualDub, but never got around to using the full potential of it. Messed arround with avisynth for a week now and just love the simplicity of it: I use as simple "directshowsource" script to load my HD mkv- or mp4- files (anything goes really) into vDub and find the frame-numbers for my cuts, use the Trim (xxxxx, yyyyy) ++ in a new script and which can be loaded directly into my Xilisoft converter. Makes it really easy and very flexible to get from any video source to something that facebook will show in "HD".
I never got DGIndex to work but i can just cut and paste the numbers for now.
