Hi, New problem; when i open up an existing project - FCP stalls for about 10 seconds and then everything in my sequence becomes unrendered (red) and i get a "cant locate media" message. Reconnecting media does nothing. Scratch disks are set correctly. I'm not getting the usual MEDIA OFFLINE warning when i select individual clips. if i try to render the clips, the picture clips will render but my song/soundtrack underneath will not. If i pull the song out and move it in the sequence, isolate it away from the other clips, then it does render. But I cannot make it render while it is part of the video - ie. while there are picture clips sitting on top of it. I have played with sequence settings recently because i needed to make an NTSC DVD, but i have returned all my settings to normal. (I import HDV 1080i, i'm based in Sydney, AUS) I also use multiple hardrives for different project but always re-set scratch disks. I use FCP 6. Any thoughts? Thanks for your help.
