My MPEG-2 DVB and ATSC transport stream tools:

epid - erase select programs in a multicast stream so that it will compress better

atrim - trim (edit) ATSC streams

ec - count the transmission errors in a stream

fix1088 - change the vertical_size_value in the MPEG-2 video sequence headers from 1088 to 1080.  This will remove the grey bar that you see at the bottom of some 1080i broadcasts.  Specify the video PID on the command line.
