A:AnswerI used it with windows 10. I also tried to use it with an older macbook and had no problems. the problems is what operating system for mac you use.
A:AnswerYes I was surprised to find that it worked very well as a plug and play on a Macbook Pro. It didn't even need to install drivers, it just worked.
A:AnswerI would think that it would work if the signal were available as a USB port. If your Direct TV does not have a USB output then you would need an interface device or record from your PC. Nero and other vendors support recording from VCR and other sources and I would think that you could get an adapter that would work. Search Amazon for "VHS to DVD" converters.
