I am somewhat disappointed that I can't find a DVD recorder that does what I want. Maybe I just don't know about it. I consider it a must to have: 1. Ability to recorder Dolby Digital 5.1. I have seen many machines that record Dolby ProLogic. 2. Ability to edit out commercials precisely. In other words remove the commercials to the exact frame. I have a Dish Network DVR, so I really don't need or want a hard disk on my DVD recorder. I just want to be able to transfer my recordings off of the DVR to the DVD recorder, with all of the video and audio resolution and be able to remove commercials.
