Someone sent me two new MOV files today. I installed Quicktime 7, it played the two MOV files, but VIDEO ONLY. No sound. HOWEVER, I can see the sound levels jumping in the video window, but hear nothing.
I tried a different MOV file I had on my HD from a different source -- which does have sound on the sender's PC. Same issue.
I tried playing some other files, MPG files, with Quicktime 7, and they play fine - WITH SOUND.
I also tried playing an AVI file with Quicktime but it says I need to download more stuff, so forget that.
I tried playing the MOV files in PowerDVD, Windows Media Player, and Winamp, but no go.
I tried opening the MOV files with virtualdub mpeg2 (which is the only version of virtualdub I can find nowadays). Said it couldn't open it. LIkewise, some EE Posts on related subjects said try using "GSPOT" to identify needed codecs for MOV Files -- but GSPOT said MOV is an unsupported file type!
Some people on web said this issue (no sound for mov files in QT7) might be caused be various codecs used when recording, or when converting file.
Other people who had similar problems said the MOV files DID have sound with earlier versions of quicktime.
I'm trying to avoid installing a hundred codecs and/or versions of quicktime.
So, to recap, my Quicktime 7 won't play sound on MOV files, although the sound level indicators are jumping. But Quicktime 7 DOES play MPG files with sound fine.
Anyone recognize these specific symptoms?
