Can someone confirm what the audio delay settings should be on an Arcam DV27a if I'm not using progressive scan? I'm not talking about the settings for individual speaker outputs: there's a double "slider" control (one for PAL, one for NTSC). Also, does anyone know what the latest software/firmware versions are for the DV27a, and where they can be got from (without bothering a dealer)? Finally, is there a list somewhere of how to get into all the "hidden" or "service" menus on the dv27a? I'm aware of the FAQ at http://www.envytech.co.uk/arcamdvd/ but this isn't very up-to-date (and doesn't seem to contain quite as much info as it used to).
