I have discovered a flaw with the cheaper software. When you burn a film there is a lack of syncronisation with the sound. I use the software which came with the machine and there is a split second discrepancy. But others have reported here that it can be up to five seconds. I got hold of an OEM version of Nero which burnt to my DVDRAM which plays alright on the computer but the player won't recognise it. Probably a case of perservering.
