I'm curious, is it possible to save say 5 minutes of say an hour DVR recording or when you erase the recording do you have to erase the whole thing? If you can save just parts of a recording can someone please tell me how to do this. Ordinarily, it wouldn't make a difference as I could just record the part I want into my DVD recorder, but its in the other room attached to my other DVR & I don't want to detach it right now.
