Query: Worthless junk

I bought this unit at Costco since it was about 50 dollars cheaper than the others I've seen. Out of the 12 dvds I've made so far, only 4 work. The unit repeatedly froze up either while updating the disk after a recording or while finalizing a disk. Out of the 8 disks that did finish finalizing successfully, only four of them worked. The player would say that the other were Blank discs, but if you tried to write to them it would say the disc is full.I will be returning the unit for the second and last time. (First one stop displaying video altogether after the 3rd day)
