Some follow-up for everyone. The AMC 2 that comes with the Pilot CAN be upgraded to AMC 2.5 for the $14.99 upgrade price. To upgrade you have to go into one of the .SET files in the installation folder of AMC 2 and copy the serial # so you can create an account at Arcsoft.com and register your OEM version of AMC 2. At that point you can choose to upgrade and get AMC 2.5. I'm at work so I don't have the name of the file with the serial # in front of me but if you want specifics just PM me.
Before upgrading to AMC 2.5 I downloaded the trial and used it to rip, convert and transfer several DVDs to my Pilot. No A/V synch problems with any of them and it worked very quickly. It's a nice one stop solution.
