Well my DVP-CX850D has been up and running for 10 days. It is integerated into the PC control system which mintains the disk library. I wish there was some way to direct access a slot without going through the disk explorer display.

The main feature I don't like is the auto play of the loaded disk on power up. The currently loaded disk is the one we watched last night!

For you Pronto Fans, the device code is 2362 (same as all other DVD players)and the majority of the codes are the standard sony key codes. I have the codes mapped from the remote and will begin searching for new codes (undocumented or not on the remote) in a week or two when I get some time. They use a second device code for the dual function keys (3162) when in the Explorer setup mode.
