> 1) If I create an HD project in Vegas, but burn it to a normal DVD-R, will it play? Since DV is a lower resolution, perhaps this just means that I render the final project to a DVD-R compatible MPEG, yes?
Yes, you have to render your HD footage to a DVD compliant MPEG2 file.
> 2) The HD will be 1.77 aspect ratio, 1280×720 pixels. If I create my Vegas project with this setting, will this automatically create a non-letterboxed true-widescreen video format for both HD and DVD-R, no matter the level of render resolution for each output format?
Yes it will create true widescreen 16:9 non-letterboxed output. One thing to be aware of is that DV/DVD Widescreen and HD Widescreen have slightly different aspect ratios that are both called 16:9. HD media will show slight black pillarbox bars in a DVD widescreen render unless you crop or stretch the video. Personally, I use the stretch option when I render and it looks fine.
> This paragraph confuses me quite a lot. How does one deinterlace before you even being editing? What does that mean?
They are just saying that if your output is progressive you might ant to deinterlace any interlaced footage before you start editing and work entirely in progressive mode. That requires you to re-render your source. I don’t believe this is necessary (at least not for Vegas users). Vegas handles mixing interlaced and non-interlaced footage quite nicely. Some other NLE’s do not.
> Considering that I am interested in 2 different output renders (HD and DVD-R), how should I approach this deinterlace issue?
Since you said that your project is comprised entirely of photographic stills and these stills by their very nature are not interlaced, I would work in progressive mode (progressive project settings and progressive render settings). Both of your output formats support progressive 24p rendering so there is no need to interlace at all.
