Here's what I've had the most success with:
1. Edit commercials and create mpeg with VideoRedo
2. Open, chapterize, menuize, burn DVD with Nero Vision 4 (if file is too big, I burn an image to disc and go to step 3.)
3. If needed, DVD Shrink and burn DVD.
I have tried editing with Dcut and/or edit/burning with Nero, but I had sync issues until I downloaded the latest Nero update a few weeks ago. But even with Nero, I never have liked Nero's video conversion of the dvr-ms file. Seems like Nero converted mpeg2 created some weird reoccuring horizontal interlacing lines that I couldn't seem to get rid of. So I have stuck with VideoRedo.
I have used Graphedit, but I really like the control that VR has.
I have noticed that recording 2hrs NTSC in best quality settings tends to create video larger than a regular DVD and Nero Vision 4 can't automatically resize it. However, with ATSC recordings, Nero can resize it. Weird eh?
