I'm currently using dvd-slideshow to create video files containing slideshows with sound, transitions and titles, and I'm quite fond of the command line approach for this kind of task. Is there any good alternatives to dvd-slideshow for this kind of task, if so which? Or should I stick with dvd-slideshow?

As mentioned I appreciate using the command line for this kind of task but it's not a necessary – I'd be happy with a good GUI too. Also, I'd appreciate further options and customizability than what dvd-slideshow allows for. Finally, I'd appreciate answers with arguments for a certain application or comparisons between certain applications.
