Dear Laurent, The problem you have could be related to an MPEG parsing error in mplex if you are using the stable 1.6.1 or 1.6.0 mplex. This has been fixed a while now in the CVS development version. Otherwise I'm just not sure what the issue could be A

y not noticeable over default. If you are encoding non-interlaced material you can also use -I 0 which makes things much faster by skipping the special interlace motion estimation calculations. Cost in quality should be zero (given the right material). Andrew -
