First, for DVD's, assuming you have a DVD player which supports using FFDSHOW as a filter.

1. Blur & NR - Enabled
- Disable everything from the settings, except for Denoise3D and HQ, they sould be enabled.
- In Denoise3D settings, put Chroma to 1.00, Time to 4.00 and Luma to 0.00.

2. Resize & Aspect - Enabled
- Resize on, Multiply by 3 if your computer can handle it, 2 if it can't, or even some specific resolution will do. (The point is to resize the video to be bigger than your viewing resolution, which the video card will then scale it down to. For some reason, this gives you better IQ than just resizing it straight to your native resolution)
- Enable Resize Always
- Aspect Ratio should be changed when needed, if ever, but 'Keep original aspect ratio' is a good default
- On Resize & Aspects Settings sub-page, set both Luma and Chroma methods to 'Lanczos', and make sure the Lock is enabled. Number of tapos should be set to 2.00, Luma Sharpen to 1.00-1.50 and Chroma Sharpen to 0.00. Enable Accurate Rounding.

4. Deinterlacing - Enabled (Note, this is heavy filter)
- Set it to Framerate doubler, and 'no motion estimation - blend images'

All other filters should be disabled.


Then the settings for other videos:

1. Postprocessing - Enabled
- Set the Presets to far right, with Automatic quality control enabled.
- Set Processing method to 'Mplayer', and use 'Accurate Deblocking' if it works for you, this seems to change from build to build and video to video, for the ones it works, it's great, for the rest.. well, not so good  Use Level Fix settings if needed, this can however cause over emphasizing of contrast.
- SPP Deblocking is a really heavy setting to use, and broken on many builds too it seems. It should be, however, used on really low quality videos if possible, on higher quality videos avoid this, it gets rid of too many details easily.

2. Blur & NR - Enabled
- Disable everything from the settings, except for Denoise3D and HQ, they sould be enabled.
- In Denoise3D settings, put Chroma to 1.00, Time to 4.00 and Luma to 0.00.
- In case there's too much noise in your video, try rising the Denoise3D settings, Chroma up to 2.00-3.00, Luma up to 1.00-2.00 and Time up to 5.00-6.00

3. Resize & Aspect - Enabled
- Resize on, Multiply by 3 if your computer can handle it, 2 if it can't, or even some specific resolution will do. (The point is to resize the video to be bigger than your viewing resolution, which the video card will then scale it down to. For some reason, this gives you better IQ than just resizing it straight to your native resolution)
- Enable Resize Always
- Aspect Ratio should be changed when needed, if ever, but 'Keep original aspect ratio' is a good default
- On Resize & Aspects Settings sub-page, set both Luma and Chroma methods to 'Lanczos', and make sure the Lock is enabled. Number of tapos should be set to 2.00, Luma Sharpen to 0.50-1.50 and Chroma Sharpen to 0.00. Enable Accurate Rounding.

4. Deinterlacing - Enabled (Note, this is heavy filter)
- Set it to Framerate doubler, and 'no motion estimation - blend images'
- If your video really does need deinterlacing, TomsMoComp with Search effort set to 3 and vertical filter enabled should do the trick

Other filters should be left disabled, but if you're looking your screen from far away, adding some Noise might help it look bit better, some people get really annoyed by it, others don't. If you end up using Noise, I suggest using 'New noise algorithm (avih)' or 'Mplayer noise', and play around the settings to suit your own needs best, personally, I don't like the added noise, so I don't really know even a good baseline.
