Query: Piece of Junk - Don't buy Samsung DVD Recorders

Basically a $300 piece of junk. DV input does not work and locks up the machine. Firmware update did nothing. Many DVD movies that play just fine on other players hang and get stuck. After about 6 months of use the DVD recorder burns nothing but coasters. The is a very poor design. Samsung should be offerring free replacement/repair. A similar experience with a Toshiba model resulted in Toshiba repairing the unit for free even when out of warranty. I'll go back to buying Toshiba from now on. Pass on Samsung products unless you like to waste money.
