I've got the DVDM-100 and like Nick said, it just works, especially when paired with the Sony piece. I loved the Kenwood picture but the Sony changer's transport is smooth and it also "just works". I have been very pleased with it.
Escient has continually upgraded the software on the DVDM-100 adding features like Palm device control, web control (on a local LAN), etc.
I also don't cringe when I see a "software update downloaded" message like I do with some other PC or consumer electronic devices. Also, their tech support is great. These days any electronic device that does what it is supposed to without making me research every nuance of its operation is a winner in my book.
My DVDM-100 also bypasses the menu and has done so through all of the software upgrades with the Sony. At one point I was also trying to find out what setting does this and determined it must be something with the Sony changer firmware or settings as my Kenwood always stopped at the menu when paired with the exact same DVDM-100.
Most of the time I like it, but sometimes I want it to stop at the menu and I just have to hit the menu button, no big deal. But it would be interesting to see what controls this behaviour.
So Nick, do you exect a Blu-Ray changer that works with the DVDM-100 soon??!!
