Query: Samsung is a lemon brand! Do not buy from them!

First of all I tried to tuned in the TV channels, and only 3/5 of the commercial channels worked. Secondly I try and put a DVD in and the remote control is not very receptive. You repeatedly push the button and nothing happens when you try and use it. Thirdly it is slow and sluggish. Fourthly, now it won't accept NTSC and only PAL DVD's! Even though they were fine in the past. I put a NTSC DVD in, and the screen quality looked very poor and went green and now the VHS video side will work!This is a lemon this brand! I'll never buy off these cons ever again!
