For anyone reading this, I should emphasize that, in my experience, many vc1 interlaced files will work fine even with the original 0.49 build, but others won't. I don't know how to tell in advance which is which, however. It is very dependent on cpu speed. The Microsoft wmv decoder (even outside LAV Video) will have trouble with some vc1 interlaced files with all but the fastest cpu's.

That's why it's nice to have HW accelerated video using your GPU.
Tested with GraphstudioNext :
CUVID + HW interlacing 50/60 : 138 fps
DXVA-CB (no deinterlacing) : 69 fps
DXVA-CB + yadif MT (LAV) : 137 fps
It seems that yadif MT on my system can keep up with 69 fps coming in from VP and outputting 2*69 = 138 fps.
In this combination there is no noticeable slowdown because of yadif mt anymore.
It seems in general if the HW-modes can handle the stream, they don't suffer from performance degradation with certain VC-1 files like the WMO does.
