Hi!
I used a script (that I copied from a howto) to prepare dvd menus.
Since some months ago all worked perfeckly, but now, when I use the 
script I read it:
Command in script:

ppmtoy4m -n 250 -F 25:1 -I t -A 59:54 -L temp.ppm>temp.y4m
mpeg2enc -f 8 -n p -o temp.m2v temp.y4m

Console:

jpegtopnm: WRITING PPM FILE

DVDStyler uses the same technique and it crashed when I try to prepare a 
menu.
I used dvd-slideshow, that use different programs but it doesn't accept 
widescreen resolution (it has no option to set the aspect ratio).
How can I find the problem?
Thanks a lot,
Luigi
