Hello, just a question to anyone who cares to answer; When I burn dvd's both on my home unit, and my PC DVD recorders, Some of my friends, (I let borrow DVD) are telling me my disc will not play on thier player. I know about FINALIZING. Even some of the re-writable disc to it to. I've asked them if they have ever cleaned thier players. the discs usually play in 2 of the other home dvd players, and PC that I have. Any ideas?? Thanks !
