Hi Jean-Yves,

I understand all of what you have stated above.
I was just trying to present a transferable metric (same tool & test data).
I have not made a study of qvdpautest, I have just used it to test my 
install is working & it hasn't been doing much of that lately.

I did state that 9400GT was not up to 2x hardware de-interlacing.

I am still using an analogue CRT, 1080i60 is the limit so I do not need it 
2x de-interlace.

Currently only using $2000 HTPC as web browser (with VGA PC monitor) & mp3 
player.
Recorded h.264 (FreeviewHD) material plays almost perfect 1080i & 720p.

Thanks & regards,
Brett.
