This is fantastic, exactly what I was looking for.
Now a suggestion, a really easy thing to add to this: Checkboxes for mpeg2source, mpegsource, directshow source (If you are going to add one, make it mpeg2source
As an addition to checkboxes for common sources, how about an input box for a custom typed source?
(What I personally really want is the mpeg2source but I'm sure tohers would apreciate other sources too)
TRhis will save me from virtually any manual editing.
Cheers
