Hi Simon,
Thanks very much for your help, I didn’t use your idea in the end but in the process of trying it out, I realised I hadn’t tagged the Type and Creator IDs properly, which is essentially what exporting with quicktime would have fixed for me. I used Quick Changer for this, its free and pretty good for fixing file types.
So yeah, nice one, cheers 🙂 saved me alot of head scratching…
Take Care,
Joe
