Created a QT movie on a Mac running OS 10.4.3 and using iMove HD - saved as both .mov and .mp4. They work fine with QT 7.0.3 player. Uploaded them to website and there's no audio on either. Using GoLive CS2 to do web page. Guessing that the browsers I've tried (Safari, Firefox, Netscape) lack a newer QT plug-in or something is lost via FTP to website? I no nothing about any probs. with latest version of QT - version I'm using is 7.0.3 that I have upgraded to QT Pro. I think the very latest version is 7.0.4 (not sure will check). Any suggestions?
