I do Author my own DVD Recordings and I have good results with the following settings
(my TV Card is Medion 2819)
Set the MPEG Settings to the following:
MPEG Format : MPEG 2 DVD
Frame Size : 720x576
Frame Rate : 25,00fps
Sample Rate : 48 kHz
Video Bitrate : 6000 KBits/s
Audio Bitrate : 224 KBits/s
Total Bitrate : 6224 KBits/s
File Split : 4063 MB
This is about enough for 1hour 30 Minutes on a DVD 4.7GB DVD.
If you have a longer Movie you can reduce the Video Bitrate or leave it and render the generated files down with DVD Shrink 3.2 (since its free and the fastest)
free download is searchable over

For the DVD Authoring Process I recommend TMPEG DVD Author 1.6.
You can trial the Program from here:
http://www.pegasys-inc.com/en/
It allows you to just take the output from the above MPEG 2 File and Push it onto DVD with the DVD Author 1.6.
DVD Author is not free but I think its good and easy
. It allows to create Menus and Animated Chapter previews.
I hope this helps with the recording
