I went the other way with an Artec recorder ($129) and an internal DVD recorder for the PC (less than 50.)
I want a dvd recorder mostly for tv shows, but would also like to be able to burn edited videos from my computer. I've tried a tv tuner for my computer, but I don't like the quality. Is there a dvd ram recorder out there that will take a usb from a computer? The only info I can find is pluging in a camcorder. A store clerk told me the Toshiba rs-tx60 will work, but Toshiba's website says nothing about it.
