frames at their very end, which probably doesn't matter. At any rate, if you have
generated an index file with VDR version 2.0.6, 2.1.5 or 2.1.6, you may want to
do so again with this version to make sure the index is OK.
- Added the new command line option --updindex, which can be used to update an
incomplete index of a recording (based on a patch from Helmut Auer).

Update the index file for the given recording.

The recording must be in TS format.
If the recording already has an index file, it will be checked
whether it is complete, and will be updated if it isn't. If
there is no index file yet, a new one will be generated.
The program will return immediately after updating the index.
Note that using this option while another instance of VDR is
