Jean-Yves,

My issue is that under MythTV for VDPAU decoder I can choose only with:

Bob (2x HW)
One Field (1x, HW)
Temporal (1x ,HW)
Advanced (1x ,HW)
Temporal (2x ,HW)
Advanced (2x ,HW)

I not looked into sources, but "HW" suggest me that all those 
deinterlcers are realized in Nv gfx driver/hw - not in MythTV. So for 
non-nv hw/blob they are not working.
On-screen result on AMD/ATI are conforming this: no mater what I select, 
AMD/ATI gives me no-deinterlaced picture.
Maybe I miss something?
