The VC-1 decoder used in both DSS() and DSS2() is the one from WMP11.

Who is right here?

eac3to and DSS()
or
DSS2()

And why the difference?

Who is right here?

eac3to and DSS()
or
DSS2()

Probably eac3to is right.

Build a graph in Graphstudio with a better VC-1 decoder (ffdshow, ArcSoft, Sonic), then use DirectShowSource() w/

«fps=##.###, convertfps=true»

And why the difference?

Read again my previous post. :)
As I said, the DMO decoder can generate a sort of "decoder lag" for some streams.

But I used the WMP11 VC-1 decoder for both DSS() and DSS2(), so how come the 1 frame difference? :(
