Ok,I use avi2dvd just so I can convert video files into VOB files so that I can burn it on DVD.I have 6 episodes to convert and the videos were joined perfectly and the encoding was also 100 % successful.Everything looked perfect but when I open the VTS folder to open the VOB file,only 3 episodes arer played.Where did the other 3 episodes dissapear to?I swear the encoding was 100 %.And then when I tried converting 4 episodes,only 2 episodes are played in the VTS folder.Why is ithis happening?Is there any way that I can convert all 6 episodes and not just half of them????

If all episodes were joined they should be in the output directory, use software like power dvd to play output files from hard disk and check how many chapters are there and what is the duration.
