I can not get .mp4 files to play in media player classic. i have installed every codec pack known to man but .mp4 files still will not play with media player classic. i can get them to work with VLC, but i do not enjoy using that player for many reasons and would much rather use media player classic. i dont understand, i have never had any problems with any other video format before, just this one video format. these .mp4 files are giving me such a headache. ive been to free-codecs.com and downloaded every codec pack there, and also everything under tools. i have also downloaded some other codec packs on other sites, but nothing works. i even checked in my system32 folder and i have at least 4 different kinds of mpg4 .dlls.media player classic is the best media player in my opinion and i would really love some help. why cant i play .mp4 files in media player classic? thanks for your time.
