Problem with FLV files

Hello,

I'm having trouble with importing FLV files into Director 11.5. When I import them (as linked files) it was creating a hard black line (around 5 to 10 pixels) on the right and bottom of the video.

I put them into Media Encoder and converted them checking the "include alpha channel" option. Now when I import them, I get a dirty white edge on the videos. Basically, some of the pixels are white and some are light gray.

Any thoughts on what could be happening?

Thanks for your advice.

Todd
