I am planning on buying a dvd or a dvr recorder , but not sure which way to go. I was looking at the LG lrh-539 or the LG lra-536. I want to be able to record ppv ,and was told at another site that they can both copy without having copyright blocking them, because they are fed with coax,s vidio or rca cables which I am told is anolog so no problem. I have read from this site that I will have a problem. What is right ? Do I have to run Sima or something like that ?
