I've browsed some of the other posts on this topic. I'm researching this for a less than tech savy friend. He tried pressing play on the dvr and record on the dvd recorder and he claims it did not work. He has the fios dvr from motorola, and a cinevision rv 4000. I know on my scientific atlanta there is a option to copy to vcr and u can use the dvd recorder as the vcr. I'm not familiar with the fios hardware. Any help would be greatly appreciated.
