Large Capacity for Mass Storage (HDD) The HDD of the DR-DX7 boasts a huge storage capacity of 250GB, enabling up to 473 hours of recording*. You can save a large number of TV programs or other video content, and transfer as much as you want to DVD discs for archiving and/or playback on various compatible players. It's also convenient when you have to be away for an extended period of time, but you don't want to miss any of your favorite TV programs. Moreover, JVC's Hard Disk Drive automatically activates "Temporary Loop Recording" when the unit is turned on. This function lets you "go back" and watch or record a program you missed without loading a disc or setting the timer, because it records TV programs up to a specified number of minutes/hours in a continuous loop. * HDD capacity will differ among products.
