Sample video render not playing the dvd file

Hi ,

The sample video render from Direct X 9 Multimedia\DirectShow\Filters\SampVid
it renders all the files like
1.mpeg
2.wmv
3.mp4

but when I connecting this sample video render to the powerdvd decoder it gets connected
properly,but when i play it I can neither see the video nor I can hear any audio.
But when I connect to the powerdvd to the VMR7 through graph edit with only one pin (video pin) its starts playing,can any help me what should be handled in the sample video render code to play the DVD files also

Any suggestions will be a great help for us

Thanks & Regards,
Raghav
