I have not updated my firmware yet, but other then taking a shot in the dark to get the menu into English everything was okay. The English menus are not hard to understand or at least i have not had any issues.
What is the most up to date? My videos say VicoTag6. I i am on 6.1. I seen the DCT in depth provieds a link to the most current, but does not say version number i don't think unless i missed it. File is just sd_vicotf2p
