    QuickTime works just fine with all formats on Lion for me. So it's definitely not a Lion issue.

    Also Can't play .mov in Lion

    I, too, can't play .mov files in QT 10 since upgrading to Lion. They open in QT 7 fine though. I haven't investigated the cause yet, just chiming in a "me too".

    I couldn't play an M4V I ripped myself. It played fine on Snow Leopard in QuickTime X, and VLC plays it fine even on Lion. QuickTime X in Lion just doesn't play it. It plays everything else I tried though.

    my *.mov file is created with previous version of QT (snow leopard)…

    so…there aren't any solutions yet???
