Is it me or did you lose some of the advance editing features with the newer model of the cyberhome line of recorders. With the 1600 you cannot manually edit the chapters like you can with the 1500 and that is something good? You are stuck with where the unit auto places chapter markers instead of where you want them. Here is a review from Amazon.com on both units..... [ with most items when you get a newer model it has the older features as well as newer ones or improvments ] however with Cyberhome that is not the case. Read the product reviews below. I wish I had known this unit did not have this feature otherwise I would not have purchased it and took my chances with a bad power supply.


Amazon.com Product Description
One of the most affordable stand-alone DVD recorders to date, the CyberHome CH-DVR 1500 offers DVD+R and DVD+RW recording and high-resolution progressive-scan DVD playback, making it equally well suited for recording TV programs, archiving your home videos, and enjoying your favorite movies on a high-definition or HD-ready TV. As it's increasingly more common for standard DVD players to play DVD+R/+RW discs, this is a great way to share personal footage with distant loved ones.
With the CH-DVR 1500 you can digitally record superb picture and sound--up to six hours a disc, in your choice of resolution (only one hour at the highest-quality setting). Use the timer and scheduler for advance recording of up to eight favorite TV programs, or record "live" to disc at your whim. The recorder lets you add markers and thumbnail images with auto chapter or set chapter markers manually.
A major benefit of the DVD+RW (rewriteable) format is the ability to edit programs as you're making a disc, ensuring through handy add and delete buttons that you'll only commit to disc the segments you intend. Further, there's no finalization required before playback of DVD+RW--you can use DVD+RW discs pretty much the way you use VHS videotape, only without the cumbersome fast-forwarding and rewinding. DVD+R lets you edit--add, move, remove--but you can't reclaim recorded space once it's been burned, so your total disc length shrinks as you make cuts.
Front audio/video inputs (composite- and S-video) accommodate feeds from camcorders and other devices, and the recorder offers 9-bit analog-to-digital encoding from video sources. An onscreen disc title navigator gives you quick, easy access to your recordings.
As a player, the unit handles everything from DVD+R/+RW, DVD-Video, and DVD-R to VCD, SVCD, and CD-R/CD-RW, including CDs filled with MP3 music files. Progressive scanning doubles the scan lines of an interlaced signal by scanning all 525 lines in 1/60 of a second for each full pass. The higher-density video signal creates film-like DVD images with rich detail, extraordinary depth of field, and precise color reproduction.
Composite- and S-video outputs accommodate most televisions, and a choice of either PAL or NTSC video output lets you use the player/recorder with either monitor type. The unit offers an RF passthrough for TV tuning, but be aware that this channel signals from the onboard NTSC tuner only--not from DVDs. If you have an older TV without a composite-video (yellow RCA jack) input, you'll need an RF modulator to go between the DVD recorder and your TV.
