It is hooked up with composite right now because using an HDMI I wasnt getting any sound. The reason for that was explained above. But still, the way it is hooked up right now is DVR to TV with composite and DVR to DVDR via analog from the DVR output into the DVDR input. Thats not working. When she records its just blank air.
Your terminology is a bit confusing making it hard to visualize how you have things connected. The way you worded things makes it sound like you've got analog video to the TV (but no audio) and analog audio to the DVDR (but no video).
'Composite' refers to video - a single cable with a yellow connector (although the color doesn't really matter, it's just a convention). This is analog video.
Analog refers to analog audio - two cables, one with a red and one with a white connector. Although composite video is analog too.
So you need all three cables from the DVR to the TV and another three cables from the DVR to DVDR if you wan to go the all analog route (which you probably have to since the DVDR is not going to record digital audio or video).
Now if you actually do have the connections right, another potential problem is the resolution setting for the DVR. By default the SciAtlanta boxes set the output resolution to 'Upconvert 1' which IIRC is 1080i. The DVDR is only going to work with 480i. You should change the DVR setting to 'Pass-thru' which means it won't touch the resolution of any signal coming in. Pass-thru is actually better for most HDTVs anyway because the TV generally does a much better job of scaling and/or deinterlacing than the cable box.
One caveat: although all outputs of the DVR are active at the same time, it may or may not downscale 1080i to 480i at the composite video output. If it does, you should be able to record an HD program (although in SD). To test it out, try viewing both an HD channel and an SD channel.
