Single-line AVS file: DirectShowSource("Man Down.S01E01.mp4")
Drag-and-dropped onto VirtualDub 1.10.4. Windows 7 Pro. Result is dialog box shown in attachment.
Sorry, not an Avisynth problem it's a DirectShow infrastructure problem. Use something like GraphEdit to test your DirectShow environment.
Google for "Error code e80040266 pins cannot connect due to not supporting the same transport."
Given you are on Win7 you probably only have newer MediaFoundation components (codecs, spliiters, etc) installed you need the older DirectShow components. You will probably need to investigate a DirectShow merit switching tool.
Other source tools like FFMpegSource, LWSmashSource or DGSource do a much better job of opening various media files. DirectShowSource should be the last ditch attempt.
