I recently have restored my comp. to factory settings ( erased) I can play cd rom, and audio but can not play movies. I have downloaded drivers, patches, players, and codecs but my comp. freezes when I try to play a movie. This all promted when I bought a new cell phone that allow playback of mp4 and 3pg- My intent was to convert my honeymoon and wedding video to mp4.. format but when I inserted the cd's it froze I freaked out thinking our movies were damaged but, they do play on alt. machines. I dont know why or what went wrong but I guess my goal is to play these videos on my comp. I have included a system snapshot if it will be of any help.
