The RDR-VX500's editing options are par for the course. You can review recorded chapters and snip out segments (good for deleting commercials) and add and remove chapter marks, or the deck will automatically add chapter marks every 5 or 15 minutes. Provided you're using a DVD-RW disc in VR mode, you can also create playlists that let you edit or shuffle chapters without altering the original recordings.
The deck's set of connections is good, although not as complete as we'd like to see. In back, you'll find component-video, S-Video, composite, and RF outputs, along with analog and optical/coaxial digital audio outputs. Inputs on the back panel are rather light: just one composite A/V and one RF--a disappointment for anyone who wants to connect an S-Video-equipped satellite or cable box to the Sony's rear. The front panel is well connected, however, with a composite A/V input plus S-Video, as well as the aforementioned FireWire port for pristine recordings of digital camcorder footage.For our VCR-to-DVD dubbing test, we dredged up a 12-year-old VHS tape that was originally recorded in the two-hour SP mode. Our SP-mode DVD-RW copy exhibited rich and vibrant colors, but it also faithfully reproduced the tape's considerable video noise. While we've seen other VCR/DVD combos that did a better job of reducing the shimmering veil of VHS noise, they tend to darken the picture or dull the colors in the process; either way it's a trade-off.
We tested the RDR-VX500's recording quality using the S-Video input on the deck's front panel, and we were pleased with the results. In our resolution tests, the recorder captured more than 450 lines of horizontal resolution in the one-hour HQ and 90-minute HSP modes, as expected, while we detected some slight artifacts around the edges of objects in the two-hour SP mode. Resolution plummeted to about 260 lines in the three-hour EP mode, making for a much softer picture, and we saw big, blocky MPEG artifacts in the eight-hour SLP mode--no surprise there.
The deck's recordings looked just as good with actual programming. In our test recordings of Star Trek: Insurrection, the peasants fleeing from the murderous probes looked clear and detailed in the HQ and HSP modes, as did the smoky, tough-to-render scenes of the damaged Enterprise bridge. When we dialed down to the two-hour SP mode, we noticed a little blockiness in the backgrounds and murkiness as the peasants ran across the screen--again, not that unusual. The picture became much softer in the LP mode, while our SLP recordings were unsurprisingly jittery and marred by severe MPEG artifacts.
The RDR-VX500 had no trouble with our 2:3 pull-down detection test, handling Insurrection's jaggy-baiting haystacks and bridges with nary a hiccup. The unit performed well in our DVD playback compatibility tests, although it did fail to handle one relatively easy DVD+RW disc.
