Samsung DVD-V3500 Progressive-Scan DVD/VCR Combo
This is the one you have all been looking for!
After much debate and research on many different models of VCR/DVD combo units I decided on this one because it had all the features I was looking for, auto-tracking, 7-event programmable timer, view DVD while taping on VCR, ability to connect to an OLD tv through only one RF cable and still have good picture on both DVD and VCR (with modulator).  After using this unit extensively for 1 month I have had no issues at all in recording, viewing or anything else one may do with their unit.  It records on time, plays back as if I were watching my digital cable, plays DVD's beautifully, and performs better than I could have expected.  <br />One of the reviews mentioned that the remote was counter-intuitive, WRONG!  This remote is so intuitive you don't really need the manual, and the menu screen is so easy to navigate.  Another review said the remote doesn't work at less than a dead on angle.  That is also, WRONG, I have used it from a very sharp angle of about 30 degrees and it responds every time.  <br />For these and other reasons this DVD/VCR unit is AWESOME!!!  If you are comparing to others stop and buy this one!  You won't be sorry!
