I am interested in getting the Panasonic dmr-e20. I tape a lot of tv shows off tv. How is it to record tv shows using the Panasonic? Also, how does it work if I am only taping a one hour show on a 2 hr disc? Can I not finalize a disc until I use the next hour?? ps-How is it to put in chapter stops? Do you do it at the end or as you are recording the show?
