Terje, I tested the Quicktime for Linux format fairly extensively. The below spreadsheet compares the compatibility of different audio/video codecs in the Quicktime for Linux container format: http://content.serveftp.net/video/qtcompatibility.ods.html
In that doc, I show compatibility for a project in DV format and a project in HDV format. The doc is pretty wide, so it helps to view it across two monitors. If need be, the Open Office version is here: http://content.serveftp.net/video/qtcompatibility.ods scott -------------- Original message ---------------------- From: "Terje J.
