I've had a lot of success with a program package I got from a link on doom9. It is called DIKO free 0.73 and is excellent in terms of the quality. It is also all legitimate free software. It does take a long time to convert, but creates DVD videos at about 2-3Gb per hour which scan through (forwards and backwards) and have fixed 5 minute chapter points. It is useful to have a copy of VOBedit and IFOedit if you are joining several smaller clips, as otherwise it will just play the first one on a standalone unless you catch the track forward button at the right moment. Downsides are the time to convert (usually about 2-3 hours per Gb of finished video) and the fact that the conversion process needs about 15-20Gb of space to write to. Don't worry though as you can delete all of the stuff it creates except the DVD Video files which you want to burn!
