Got my review copies and am very pleased.
Both are indeed 4:3 and A BOY NAMED CHARLIE BROWN is PROPERLY framed at 4:3. Looks like a new master judging from the ancient MPAA "G" rating logo that precedes the Cinema Center Films opening also. (Runs the full 86 minutes)
5.1 and 2.0 audio options and no extras -- but both look like good, natural, filmic transfers in the right aspect ratios as well.
