I'm using a Mac Mini (2010 model, 2.4 GHz, 4 GB) and EyeTV softwarewith a Silicone Dust HD HomeRun for my PVRconnected to an LG LX9500 LCD TV. My video source is OTA DTV and so far (I've just set it up two days ago) it seems to working fairly well. Now, in the EyeTV preferences there are a few choices for de-interlacing HD programs, topping out with processor-intensive progressive scan. So, my question is this: does it matter if I de-interlace at all (through EyeTV)? I'm recording from 1080i source, the Mac Mini itself outputs (thanks to Apple's new options) at 1080p, and the TV is locked to progressive thanks to the Mini's output. Is it worth it to take the processor hit for progressive? Is it worth it to even change the setting from "no deinterlacing" considering the source?
