Just recently purchased the above DVD. Noticed that I do not have the latest firmware, 5.08. Can I upgrade it myself or do I need to go to a dealer? Also, on page 8 of the manual it talks about audio delay on the 3/7 screen setup. either normal or progressive. I do not see that option. Does anyone else see this option? Also, I am interested in how users have connected this player to enjoy DVD-A ? Finally, the progressive scan option. Not sure I undertand what it means on the 2/7 menu when it states that you can change to support progressive scan. Can anyone shed some light on this?
