Play MPEG-2 using MS Windows Filters

Dear all,

I want to play MPEG-2 video using these filters:
File Source (Async.) -> MPEG-2 Demultiplexer -> Microsoft DTV-DVD Video Decoder -> Video Renderer

When I create this graph in C# using DirectShow.NET, I get black screen. Do you have any idea why?
I read something about push and pull but didn't get anything.

By the way, I played a MPEG-2 video using RenderFile function and then went through it's Filters using EnumFilters. The filters used by RenderFile was:
File Source (Async.) -> MPEG-2 Splitter -> Microsoft DTV-DVD Video Decoder -> Video Renderer
Should I use Splitter instead of demultiplexer?

Please help me on this:confused:
Thank you guys;)
