I've been looking at the decoder properties for my PVR software and there's a number of settings that I think could be tweaked to produce better results but I'm not sure what I should choose.

Quality: "Obey quality messages", "Decode I frames only", "Decode I,P frames only", "Decode all frames"

Deinterlace: "Weave", "Vertical filter", "Field interpolation", "VMR", "Auto"

Condition of deinterlace: "Always", "Interlaced frames", "Progressive frames"

What do you suggest as the best choices?
