Video Mirror Driver and DDRAW?

[Marton Anka]

Hello,

I'm having a problem with our mirror driver, which is based on the DDK
sample. When the driver is active, some media player applications won't run
citing that overlay support is not available. Indeed, when the driver is
loaded, the DirectX Caps Viewer reports no overlay capabilities.

I don't mind if, when the media player is run, the mirror driver does not
see anything but the color key - it would be imperative, however, that the
mirror driver does not cripple existing applications in any way.

I wonder if the issue can be fixed by adding a dummy DDRAW interface to the
mirror driver. However, I'm somewhat hesitant to go ahead with this, as it
could be a lot of work for absolutely nothing: what if the driver is never
asked for its DDRAW capabilities and Windows simply decides to disable DDRAW
when a mirror driver is present?

Could someone in the know please enlighten me?

Thanks,

Marton Anka
