#
# Revision 1.2  2003/06/10 10:56:54  the_krow
# - Build try-except blocks around disc imports to make it run on platforms
#   not compiling / running the C extensions.
# - moved DiscInfo class to disc module
# - changed video.VcdInfo to be derived from CollectionInfo instead of
#   DiskInfo so it can be used without the cdrom extensions which are
#   hopefully not needed for bin-files.
