Hey,
1.) I record in the 4 hour setting on the recorder
2.) My recorder has a hard disk, so i record different videos on to the hard disk first and then burn sometimes 2 or 3 of the videos to dvd
3.) I duplicate at 2X
4.) Yes i do use auto chaptering i its set at 10mins
5.) No i haven’t used authoring software but am willing to try but will it produce the same quality 4 hour dvd as the panasonic recorder i am using and if so what is the best software available. Money is no Object.
6.) Yes all the disks are the same branded
