Welcome to the Forum.
Your comment concerning the AVI Video Format is â€œBetterâ€ than the DVD Video Format is your particular personal opinion. Quite frankly attempting to cramp 12 50 minutes TV episodes (10 hours of Video) on a blank 4.7 GB DVD disk is a very unrealistic endeavor.
With all the problems you are encountering (this Forum posting and your â€œAdding Subtitle to DVD burningâ€ Forum posting) indicates that you either have a problem with the particular Authoring and Editing procedures your are attempting to use or a problem with the quality of the particular blank DVD Media you are using.
The specific Authoring and Editing procedures used and the quality of the particular blank Media used are extremely important factors in the success of your Video project. If your Authoring and Editing procedures are flawed and/or you are using poor quality problematic blank DVD Media your Video project will fail to perform correctly.
Suggest visiting the Video Edit Software Forum and closely review the information provided in that Forum to assist your with the particular problems you are encountering.
