Hallo,
there are thumbnails for flv in the ms explorer view, but xnview can´t generate thumbs for flv

. So I think the codecs are ok, but xnview seems to have a different usage of them. Maybe
klite switched the preference from
ffdshow to
lav decoder in some of their latest releases and since then xnview seems to have problems (as far as my system in concerned (Win xp)...).
I don´t have any other codec-packs or players which could confuse the codecs, even irfanview is off and cleaned.
Some ideas?
Best regards
Gerdchen
