Re: Frame rate detection error?

Well, I forgot some important info: I'm using a up-to-date Debian
testing (lenny) with the following versions:

$ dvdrip --version
0.98.8
$ transcode --version
transcode v1.0.4rc0 (C) 2001-2003 Thomas Oestreich, 2003-2004 T. Bitterberg

Both came from Marillat's repository <http://www.debian-multimedia.org/>:
Package: dvdrip
Version: 1:0.98.8-0.0

Package: transcode
Version: 2:1.0.4~rc0-0.0
