Great series, has gotten far too little attention, fansub-wise.
These OVAs are the first things to watch in the entire Slayers-series. (Accidentally said the slayers movie 1 was the first thing to watch before, but it doesn’t really matter)

My release vs. what i suppose \was\ the best release (a-S):
http://screenshotcomparison.com/comparison/49226
As for why the first picture (a-S) looks more “square” than the second (Mine), it’s because they’re encoded differently, a-S resized theirs, diminished the amounts of pixels to fit 4:3 aspect, while i kept the default resolution on the DVD to keep maximum quality, while using an encoding setting that forces the video to display in 4:3 in any video player. Thus max quality + proper aspect. I do this for all my DVD releases which are supposed to display in 4:3, and the same just display them in 16:9 when they’re supposed to be displayed in 16:9.
