i have had mine for over a year now and never had any of those problems. you just have to set up the unit correctly to play what you want. i did have a small problem with the audio on the dvd but after finding the correct setting then all was well. the karaoke part worked great as well and even read my own karaoke disks i made myself as well. the pitch control was perfect and did not hurt the song itself or speed. the echo effect worked well and it allowed for 2 microphones that came with it when i bought it. the tray for the disk worked great as well. if you read booklet it tells you not to set anything on top of this unit as it will effect the free motion it needs to eject and take in the disk. sitting something on top of this unit causes pressure on tray and when it tries to open it puts strain on the belt and will stretch it so soon the try will not close on it's own. if you read and do as it says and take care of it along with not sitting things on top of it. this unit is perfect in my opinion. the karaoke part works great as well as the dvd part and the picture is awesome too. the only thing i did not like about it was the microphones included. they work ok but i went and bought 2 shure pg58 mics which worked perfect for this device. so all in all i have to give this item 5 stars........... but i wish i could give 10.............. note people just need to read the directions all the way to set this up and it will work great. i found those who complain just lay the instructions down and then play with it. then when they find it will not work right it is the device and not them forgetting to really read the instructions. so as long as you read and do what it says you will have a great device to last you for a long time. mine still looks and works like new! still wish i could give it 10 stars LOL.
