Yes, I agree, but I wasn't comparing DVD to HD. I was pointing out that the DVD drives bolted inside some of these TV's are not necessarily the same as laptop
USB DVD drives. Instead, they may be "home" DVD systems stripped only of their cases, but containing their own power supplies, conversion chips and circuits, sound and video outputs and preamps, etc. These use a lot more power than laptop
drives for this reason.
Ours looks like this - when I peer into the vent holes, I see a large drive and associated circuits that look like it was simply bolted into the case and connected to the TV part in the same way an external home DVD player would be. And the current
draw when the DVD player is running seems to support this.
