Here are the annotated first few lines of output for a single-section 
cut from the middle of a recording:

ionice -c3 ./mythcutprojectx 1009_20100710015800.mpg 0xc9 0x191
4253 104868   # cut-in, EOF

0 92713       # Start of recording, cut-out

4253 92713 104868  cut-in, cut-out, EOF

115486708       #   cut-in, bytes. Start of output
2060170552      #   cut-out, bytes.  End of output,  58m 57s
2337428816      #   EOF, bytes
