Cooljoe815, I have a Sony KV-34XBR800. I set its Power On delay to 500 ms (0.5 sec), and its other delays to 100 ms. After a cold start, my TV takes about 12 sec to display an image, but it's ready to accept commands a lot sooner (0.5 sec). Don't confuse the inherent warm up time of a device with the Harmony Power On delay.

What is the Brand & Model of your combo DVD/VCR device (you say JVC in post #1 but Toshiba in #10)? Check its device power settings. Which method (one button for both or different buttons for each), and which power command(s). Check the behaviour of that/these power command(s) in device mode.

Also check the Watch DVD activity "Play on Enter, Stop On Exit" options (under Activity > Settings > Change Options).
