(and default to putting :vaspect=4/3 in the mpegopts in this case?) and is there a way to find out the A/R in the header and the A/R in the stream separately to confirm what's going on? anyway, thank you!! now i don't have to re-encode this film! awesome. :-D > _______________________________________________ > MPlayer-users mailing list > MPlayer-users@xxxxxxxxxxxx > https://lists.mplayerhq.hu/mailman/listinfo/mplayer-users _______________________________________________ MPlayer-users mailing list MPlayer-users@xxxxxxxxxxxx https://lists.mplayerhq.hu/mailman/listinfo/mplayer-users
