hi, to your first problem. just navigate to your avisynth plugins folder and put your decomb.dll there too. This should most likely solve your problem! 2) iirc you cannot load virtualdub filters with the normal loadplugin() command... search the forum on how to use it... anyway, i would recommend that you use vsfilter.dll (vobsub) to load your subtitles into avisynth! it should be more economic :) steVe PS: pls use a descriptive title for your post, would be appreciated if you could change this one! thx
