DVD recorder for TV use only

My wife got me a Sony VRD-VC20 for my birthday which can record DVD+R 8
GB at 4X, DVD+R at 16X, DVD+RW at 8X, DVD-R at 16X & DVD-RW at 6 X. It
is aimed at video camera applications with several standard video
inputs and attaches to the computer via a USB port. It does not have
playback. I hate to take it back because it was a present, but I don't
think it is aimed at my application.

I have the Comcast DVR service using the Motorola DCT6412. What I was
looking for was a DVD that can record certain shows that I want to
archive from my Comcast DVR. I don't care to attach it to my computer.
I figured that I could replace my defective internal CD writer in my
computer with an internal DVD recorder if I want to record DVD's on my
computer.

My guess is that I want some type of DVD recorder with playback
capability for my TV use. I don't think I need the ability to record
at more than 1X speed.

Can someone recommend a type and brand of DVD recorder for use just to
record TV programs--mostly that have already been recorded by the
Comcast DVR?
