OK
Had a play with the software, and the one I like the best is VSO ConvertXtoDVD.
Works well, and does everything I need.
Once set up how you like, converting to dvd is as simple as putting a disc in the dvdrw, Open the program and dragging the avi file into the box,
click on 'convert' and 30 mins later ( high quality) the disc is ready to play. It can be set to automatically insert chapters or menu
Managed to convert 3 different avi files at the same time too, and only took a little longer as I set the dvdrw to burn @8x to avoid buffer problems.
I have installed this for a mate that is technophobic, and he uses it without any problems with good results.
Worth a look anyway. Cheers Amph
