# This script takes a (vdr recording) filename as input and creates an index file for it,
# but only if necessary

# 1. Check if an IDX file DOES NOT exist.
# 2. Run ProjectX to split the mpeg transport stream into elementary components.
# 3. Run mplex to multiplex the elementary stream to MPEG PS (DVD-style mpeg)
# 4. Remove all elementary streams to save space
# 5. Run avidemux to create index for each fixed file
# 6. When sure... remove original recording...
