ok, here we go again...

i've manipulatet the skript something, so you can define, how many cd's the movie will need.
all your preferred setting are made in header of skript, but for myself I like these settings ;o)

i've you like restrict the movie-size to one only cd, you can uncomment the lines at the end of file --then you only have to write the moviename on cd manually ;o)
in the evening i will put this skript at my homepage, so posting on mailing-lists is obsolete.

best regards,
Andreas Reichel

# simple bash-script to transcode multiple *.vdr files to cd-sized avi-files in mpeg4-format
# use it, to convert videos recorded from dvb-cards
# use it for free, but please send me copies of modifications 
#-------------------------------------------------------------------------------------------------------------
# simple howto:
#
# 1) record the movie using vdr [1] and the linux-dvb-drivers [2]
# 2) cut the movie using vdr [1]
# 3) run this skript to convert the pva-pes formatted movie-files to ps-formated mpegII-files using 
#    pvastrumento [3] and wine [4]
# 4) run this skript in directory of movie-files to transcode [5]  
# 5) optional: burn the avi-files to cdrom
