I still prefer to leave the deinterlacing up to the person viewing it 
and not be confined to hardware limitations. I used to think Linear was 
ok until I started using Yadif. It would suck to not have that option 
now when the next best deinterlacer comes out.

Maybe one day. For now, I'm buying 1. If it works out, I'll buy another.
I look forward to getting all my capture cards out of my mythtv box and 
moving to a MUCH smaller form-factor frontend/backend box.
