Still frames before films

Hi,

I have a "best practice" question: I want to create a film with a number of 
short films. Before each film, a slide with the film's title should be 
displayed for n seconds. What's the best way to do this?

Some alternatives that came to my mind:

1.) Create a n-second video of the still image and prepend it to the video, 
resulting in a slide+longfilm.mpg.
 * pros: robust, definitely will play anywhere without side effects; can't 
easily be ripped from the DVD without the still image
 * cons: probably need to re-encode the video?; don't know a command-line 
toolchain to to this; unflexible w.r.t. new slide content or change of n

2.) Create a n-second video of the still image as slide.mpg and use
   <pgc>
      <vob file="slide.mpg" />
      <vob file="longfilm.mpg" />
      <post> call menu; </post>
   </pgc>
 * pros: very flexible: just change slide.mpg and run dvdauthor again
 * cons: Is this supported by all players? Will longfilm.mpg be easily 
rippable from the DVD without the slide? 

3.) Create a 1-second-video of the still image as slide.mpg and use
   <pgc>
      <vob file="slide.mpg" pause="n" />
      <vob file="longfilm.mpg" />
      <post> call menu; </post>
   </pgc>
 * pros and cons: as in (2.)

What approach would you suggest here? Anything else you have in mind?

Thanks for your help and looking forward to hearing your suggestions,
Tobias
