[mythtv] Seektable file vs. DB

[Chris Pinkham]

Rather than emailing since I've already had 2 people interested in
the patch, here's a link:

http://www.bc2va.org/chris/tmp/fix_seektable.diff

This only fixes the nuppelvideo format files (ie, non-pvr250) since
they are the only ones with the seektable actually inside the file.

This patch basically adds a --seek option to mythcommflag which
will read through your whole .nuv file, then re-open for writing
and write out a new/fixed seektable.  I've tested this but to be
safe you should backup your original .nuv before running.

Also, this must be run from a machine which is configured as a
backend and has access to the .nuv file to be modified.  This is
because mythcommflag uses the database to find out where the
video storage directory is located.

Usage is as simple as

    mythcommflag --chanid 1010 --starttime 20030523013000 --seek

substituting in the correct chanid and starttime.
