Strange timestamps from Decklink Video Capture

Hi all,

I build simple Directshow graph:
Decklink Video Capture -> Stream Scope(sample's analyzer)->AVI Decompr.->Video Renderer.
If I select format NTSC - 8 bit 4:2:2 YUV (not first, but 4th), then timestamps of video samples is not equal to graph time. For example video sample's start timestamp is 22.224 sec, but graph time is 48.480 sec.
In this case, I can't write correct video file if I use Video and Audio Decklink sources.

How can I configure Video Capture to avoid such behaviour?

I use v9.7.2.0.
Thanks!

Valeriy.

I'm not surprised to see there is no reply here. BM, get on the ball, this is a good question.
