I am getting quite frustrated with quicktime. after downloading many videos over the past few months, i have found that about 20 percent those dont' play in quicktime. they wont' open in windows media player or Video Lan. Before deleting the files, i tried them on a PC. and they worked! Is there a way to add codecs to quicktime? if so, how and where can i find them. also what is the best media player you khow of that can play the most file types. i just wnat to be aple to view my files!
