I have recorded from TV using RDRHX510 on a DVDRW and I can play it on my PC but how do I save it onto my PC?
You should be able to play the video file by clicking on one of the menu icons within the TS/RM folder. This is a very messy way to do things though - if like me you want to turn a DVD into a nice clickable video file on your PC you'll need some software - I use Media Factory 4 which imports the DVD in it's original quality. Then I can either rename the file and put it in My Videos folder - one click heaven, or burn a new DVD compilation with menus and all that fancy stuff.
