Re: Sony DVPC-X850D - Jury what is the verdict ?

That is correct. The minimum you have to do is start up the disk explorer, wait a bit, enter the slot number (up to 3 digits), wait a bit, press enter wait a bit, press enter. The "wait a bit" is what it sounds like, you wait until the screen (TV) shows that the operation has completed by seeing what the screen looks like. You then press the next button. No problem if you are sitting with a remote looking at the screen. Big problem if you are doing it fully with automation.
