Product ordered after a long hesitation (is it useful with a CRT?) But the price has tipped the balance. Already have a usb drive 2.5 ", the investment was less. The WD HD has two USB ports on which this type of hard drive is USB bus powered (no power cable to plug each time). Optical or RCA for audio, composite or HDMI output for the image, I admit that the composite output is already very honest quality (HDMI not yet tested). Stereo sound, Dolby Digital or DTS can be sent via the optical output to be decoded by a home cinema amplifier. This drive reads everything he is offered including and especially mkv (an exception in the world of affordable multimedia players). The high definition files to avi or mkv are read without any worry. Western Digital offers regular updates to improve the operation. I expect they restore reading cd dts that disappeared with the latest firmware. You can customize the display by inserting images corresponding to the movies on the disc and identifiable by a child (one of the objectives of the choice of this case, do not use the dvd). A community exists on the complete modification of the interface (see the homecinema forums). An expected change, auto power off when the hard disk unit is turned off and the non-ignition of the unit when you turn the power strip on which it is connected. A highly recommendable choice without real competition at this price!
