You can always re-generate the index if you have an old version of dvbcut. I just applied two patches: r132 contains the "write return status" patch I posted earlier, r133 this one. Make sure you run "make clean" before you recompile. -- Michael "Tired" Riepe <[EMAIL PROTECTED]> X-Tired: Each morning I get up I die a little ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ DVBCUT-devel mailing list DVBCUT-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dvbcut-devel
