I have a Panasonic recorder, but not one with a hard drive so can't answer all your questions, but..
- You can record programs to a DVD-R disc, eject it, record again, etc. until the disc is full. You can continue using it that way until you finalize it, which you must do before it can be played on other DVD players. However, unlike with rewriteable media, such as RW or RAM, if you erase a title from DVD-R you won't get the space back.
- Editing is fairly fast on the Panasonic if you do it by marking chapter points at the beginning and end of the commercial breaks and then deleting the commercial chapters. There is a shorten title option too, but I find it slow and awkward.
- The Panasonic does have a divide title option. I find it useful for recording back to back programs. Setting two back to back timers can sometimes result in a loss of a few seconds, at least when recording to DVD-RAM. So, I set one timer and divide the title in two later.
- The artifacts or what I call color banding is not that bad. Depending on how your TV is adjusted (sharpness, contrast) you might not notice it. It shows up on solid backgrounds which have a transition from one color to another. Rather than having a smooth transition there can be bands or steps of color changes. The banding does not appear to become part of the recording (it's not visible when the DVDs recorded on the Panasonic are played on another player.) It is however visible even when just watching TV through the recorder. In addition to adjusting the TV, changing the recorders output from normal to soft also reduces the banding.
- There is no logo, but don't give the DVD recorder manufactures any ideas.
