Looking for a DVD recorder with a built-in hard drive? CNET has a review of the Panasonic DMR-EH50 which has a 100GB hard drive and built-in TV Guide. Overall, CNET likes the DMR-EH50 and the review states:

The deck also delivered excellent recordings in our tests with Star Trek: Insurrection. Our recordings of the daylit peasants fleeing the malevolent probes looked crystal clear in XP mode, although we noticed a little background blockiness in the two-hour SP mode. The deck's LP recordings were well above par, although we detected some murkiness during action sequences, such as when the peasants were running rapidly across the frame. Our EP recordings looked much softer and juttery with severe blockiness in the background. Switching to scenes of the dark, damaged bridge of the Enterprise, we were again impressed with the rock-solid XP and SP recordings. While the LP recordings still looked good, we noticed it had a tough time reproducing the dark, smoky interiors with any degree of detail.
