Probem with Overlay Mixer + Elecard

[bda]

I have a problem.

If I lock the computer (Windows + L Key) with DVBViewer running, when I reenter, the window is black (no video, only audio).

This problem only happens using Overlay Mixer + Elecard at the same time (Overlay + Cyberlink is OK, other renderers + Elecard are OK).

If I change channnel placed on a different mux, the video works again.

Is there a solution to fix this problem? Is it a bug of DVBViewer or is it a bug of Elecard?

Thanks.

OS: Windows XP sp3

MPEG2 Decoder: Elecard MPEG2 Decoder and Streaming PlugIn v 3.7

Can I ask why you use Overlay- it is outdated, VMR7 or VMR9 would be better for XP.
