So, I exported a video, from Adobe Premiere Media Encoder, as FLV
854x480...

I have created a BEML player that has an 854x480px wide video area...

Long story short, the video was letterboxed on the sides.

I am assuming that I need to output my video as squar pixels in order
to get it to fit?

Also, the output settings I used were not far from the standard
suggested settings for 480x270 footage... I think I just boosted the
bitrate up a tad.

Looked pretty good.

Tips? Thoughts? Suggestions? Advice?
