black blocks when using mencoder

[what?]

when i use mencoder mpeg avi to encode a quicktime movie, any time the screen has 100% white on it i get black blocks on the screen. anyone know how to fix this.

also the movie is interlaced (pal). which is the best way to deinterlace this?

cheers

I didn't observe the black blocks, could you post a link to a short clip in order to make tests? To deinterlace, there is a deinterlace filter in the Filters tab.

here's a like to an avi with the black blocks:

any ideas why this is happening?

Difficult to say. If you send me the original clip I can test.

i don't have the original clip anymore. but i'll upload a clip when it happens again.
