Hi Graeme, I encoutered a situation where support of v4 device link profiles are not supported by cctiff. Are these v4 DLPs very different from v2 DLPs? I was tempted to modify the header to force cctiff to honor a v4 DLP but I shied away from it. Regards, Roger Breton | Laval, Canada | graxx@xxxxxxxxxxxx http://pages.infinit.net/graxx
