Thanks Phil - thats the question I was really asking!! - not to mention how to make the choice from the GUI with an existing recording, something I now know can't be done at present. The difference in files sizes I was looking for was in the OUTPUT files as I expected that without the -m switch I'd get a smaller file (mpeg4) than WITH the -m switch. Sounds like a feature request to me "Please can we have an option in the Previously Recorded menus to select what type of transcoding to do on the currently selected recording..." -- Robin Gilks _______________________________________________ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
