Samsung DVD-V3500 Progressive-Scan DVD/VCR Combo
On/Off Frequency Has Changed
This is a good unit at a very reasonable price.  Unfortunately, Samsung has changed the frequency that the remote transmits to turn the unit on and off as compared to earlier models (V2500, etc.).  Therefore, if you try to program another remote to control this unit, such as your cable remote, you will not be able to turn this unit on and off.  All other functions seem to work though.  Of course, if you have a learning remote, this problem is easily solved.  If you don't, don't spend a lot of time trying - it won't work.
