The very very first thing I would try is removing any crop settings and then render it. Having the “render at maximum depth” should be selected as it has no effect on crop. What do you get after you render without a crop? Then do another render with the crop settings at 14px total (or so) and compare the two.
The alternative is to just use the default and not worry about the two thin pillars on the left and right; after all this is now the standard.

Ahh, I see.. I wasn’t familiar with cropping in the export.. I just realized there’s actually a crop function on the left hand side (in the export popup window) right under the tab where you can preview the source and output.

Clean aperture:
E.4.1 The bandwidth limitation of an analog signal (pre- and post-filtering) can introduce transient ringing effects which intrude into the active picture area. Also, multiple digital blanking operations in an analog-digital-analog environment can increase transient ringing effects.
Furthermore, cascaded spatial filtering and/or techniques for handling the horizontal and vertical edges of the picture (associated with complex digital processing in post-production) can introduce transient disturbances at the picture boundaries, both horizontally and vertically. It is not possible to impose any bounds on the number of cascaded digital processes which might be encountered in the practical post-production system. Hence, recognizing the reality of those picture edge transient effects, the definition of a system design guideline is introduced in the form of a subjectively artifact-free area, called clean aperture.E.4.2 The clean aperture defines an area within which picture information is subjectively uncontaminated by all edge transient distortions.
The clean aperture should be as wide as is needed to accommodate cascaded digital manipulations of the picture. Computer simulations have shown that a transient effect area defined by 16 samples on each side and 9 lines at both top and bottom within the digital production aperture, would represent an acceptable (and practical) worst-case level of protection in allowing two-dimensional transient ringing to settle below a subjectively acceptable level.E.4.3 This gives rise to a clean aperture of 1888 horizontal active pixels by 1062 active lines whose quality is guaranteed for final release.

Scrap that idea because in Premiere CS5 if you use the MPEG2-DVD export option you cannot alter the export resolution; you must use 720×480 and this cannot be changed!
I think what you’re proposing is that you export a 1920×1080 version from Premiere and import that into Encore. Once in encore you can adjust the height by 10-12px as you proposed and transcode. But, any solution to this issue that requires upscaling pixels I’d recommend staying away from.

Ok.. I get that, but most people don’t want to upscale. The default MPEG2-DVD export is 720×480 (we all know this!) and what you’re saying is that if you change the export resolution to 720×468 that will solve the pillarbox issue created by downscaling an HD source for SD dvd distribution. However, Encore is merely scaling your footage up which reduces the quality of your image. I’m not willing to do that and I don’t consider it a viable option. This makes me wonder though, if instead of cropping you add 12px to the height if it would fill the screen; this would eliminate the upscale to the constrained SD/480px.

Yeah, but if you’re exporting to an MPEG2-DVD that means you’re exporting to 720×480. Just to clarify, so you propose reducing the vertical height of your inital composition/sequence in Premiere by 12-14 pixels; thus allowing a perfect fit when you render to MPEG2-DVD?
I just don’t get why Adobe can’t make this cut and dry. I mean, HD widescreen has been around a while now. I think Adobe is just trying to tell us to live with the vertical black bars. It’s hardly noticable on a widescreen tv anyways, but for a perfectionist I find it frustrating.

when you export out of premiere choose mpeg2-dvd. Then click on the “video” tab and change the pixel aspect ratio to standard 4:3.. This is the fix i use.. I wish there was a way to make an enhanced widescreen dvd instead of this crappy work around.
