Samsung DVD-R155 DVD Recorder

I bought this machine from Fry's back in September of 2007 for $89. Initially it worked well but after about 3 months, it would not recognize blank, new media. I tried a generic DVD-R from CompUSA, DVD-R from Memorex and DVD-RW from SONY. None worked so after numerous calls to Samsung, the Help Desk guy extended the original 90 day Labor Warranty to 180 days and I sent the machine in to New Jersey for repair. They lost my machine and finally sent a replacement, refurbished machine a little over a month later. It recorded one program using the DVD-RW and does not recognize any media now! Same problem, second verse! I have been a real cheerleader for Samsung in the past and until this fiasco, I was considering their Color laser printer, but no more! Life is too short. After my last go-around I asked if they have experienced higher than normal returns on this machine and they said "No". Of course, they are recorded (for training purposes)so I must have had miserable luck. Two machines-Two losers. Do not buy this machine!
