I use a Sony mini-dv camcorder to film amateur theatre productions which I then burn to DVD. I use Serif MoviePlus 5 for my editing and burning. I use this program because it gives me more options then Window Movie Maker and I can burn direct. I always burn an image to the hard drive first in case the actual burn has a snag. Serif MoviePlus 5 probably isn't the best program for this and Ulead may well be better.
When burning you need to check which DVD format people's stand-alone DVD players can use. Some can use the + format and not the - and others vice versa and some both.
I use my PC to add titles and scrolling credits at the end of the video and I also scan in the programme and have a mini slideshow of the programme as part of the DVD. Have to watch copyright tho!
Not sure that you can do that on a dvd recorder. I also end up watching each production as it is captured. The coding of files does take time and you need a fairly powerful PC with plenty of hard drive space.
On a recorder you can put on lots of different films. For every film you have a first frame picture shows at the startup and you can add titles to the pics, Or you can split a film in sections by stopping it and restarting the camera and leave recording going. You can edit bits out by just pausing the recording similar to the old vhs recorders. I make one dvd, finalize it then copy it on the fly on the PC.
I used to use ulead but got fed up with the time it took, although maybe you cant do as much editing and adding things, the dvd recorder is so much quicker and easy when you get the hang of it.
