Hi, Ive scoured the forum for a possible solution before posting but could not find one. I purchased the MWR20V6 twice now with the same result. Everything works fine for about a month, i.e., recording, transfer, playback etc then all of a sudden the dvd wont record. There is space left on the disk. I am using DVD RW+ and then erase when Im finished. After recording 1 or 2 shows I get cannot record on this disk error. It will not let me erase disk or programs. I put in NEW discs and get the same error doesnt matter if its R or RW new or used wont work. Any suggestions as I said this is the second unit to do this.
