Hauppage capture cards back in the day allowed dts? Or was it dolby? Look into this. The Elgato has the option to watch the preview (uncompressed) or record (h.264) also so I use the preview stream. Right now I have 480p 59.94 coming in which is incredibly GPU intensive (lots of frames plus added scaling to get non-anamorphic widescreen LD's to fill the screen). On the other hand DVD rips which get IVTC'ed to 23.98 are not near as GPU intensive (less frames plus they are anamorphic). My hope is that if I can get 480i stream direct from Eval board I can get MadVR to IVTC and lessen the GPU load. I don't know if this is possible as LD real time IVTC has always been a challenge.... The high frames burn GPU's, trying to play a rip of Gemini Man 2160p60 is laughable even for the best current gen GPU's.

I briefly played with this, and I've never seen LD look this good during live playback. Now to tackle the problem of my HTPC being a mini-ITX machine with a single PCIe slot already being used by the capture device. The onboard Intel GPU is... clearly not up to the task.
But to think I wasted all this time screwing around with the useless video settings on my AVR. I wish I found this ages ago.
I need to see if it's possible to somehow incorporate the Neat Video 5 filter into the chain before the image is passed to the MadVR renderer. It does an incredible job of eliminating chroma noise without losing detail, and transforms an LD picture into practically DVD quality, if only a touch softer. Not sure about the filter but MadVR has NR options that work pretty well also.

Not a huge deal, but it's something to look into.

The Elgato card doesn't support 480i which is I suspect why 480i doesn't really work. If its a DVD or HDDVD rip MadVR does perfectly.

What would the cost be for the MadVR set-up?

New option if anyone is interested. The MadVR Envy has very advanced AI based motion adaptive deinterlacing which HTPC does not have. This makes 480i from Kramer 773 to MadVR Envy basically the best at this point. You get the near perfect deinterlacing (better than Lumagen / DVDO / Faroudja) as well as the proven best NGU (AI based) upscaling. I didn't even buy the Envy for Laserdisc but quite ironically I found improvements where I was not even looking. The other amazing thing with the Envy is the AI based noise reduction that can work wonders for LD. Here is a quick video just showing me going through the steps of NR intensity - https://www.dropbox.com/s/x325dvd2yujad ... 9.mp4?dl=0
