I have a few mpegs of a mini-series shown on HBO at some point that are encoded very oddly. If I play them on my computer with windows media player, they play 4:3 but are stretched vertically (indicating 16:9 to me). They were encoded with small bars at the top and bottom but not large enough to preserve the 16:9 aspect ratio. If I open the files in Zoom Player and manually set the aspect ratio to 16:9 they look perfect. Do mpeg files have "flags" or whatnot that specify aspect ratio or anything like that (and what program would adjust this for me)? Failing that, is there any way to enlarge the bars at the top and bottom so that it forces the 16:9 letterboxing? I'd really rather not re-encode the whole thing as the original encoding is VERY nice as far as VCD's go.
