FFMPEG bundled with Dolphin 7.0.9 question

The FFMPEG.exe coming bundled with 7.0.9 is compiled for 32 bit Intel 80386 Linux systems and also seems to be a bit outdated. (Wasn't there some security issues with some libs some month ago?)

ffmpeg.exe: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked, for GNU/Linux 2.6.15, stripped

This makes no sense for most root-servers runnning on 64bit machines. In my case even on a AMD64.

/bin/bash: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked .....

I read lots here but no real answers, so i ask again: Is there a way to use the distros own FFMPEG package instead of the one coming with dolphin? This would have some benefits, first its always up2date and second it runs optimized for the server it's used on. So why Boonex went this way? Anybody ever tried or can Boonex provide a 64bit AMD version? Maybe i can just use a static 64 build from http://ffmpeg.gusari.org and replace the dolphin one?

There's only one way to find out... give it a try.  I think versions of ffmpeg after the one used in Dolphin 7.0.9 may not be compatible with some of the older commands/options.  If you try it, and it doesn't work, then you'll know.  If it doesn't work, it probably means 7.0.9 would need some source code changes to make it work, and since 7.1 is out, that might be a tough thing to get done.

Speaking of ffmpeg, let me ask:

Lets say I set the conversion data rate at 1000 (for video).  A user uploads a video that is 700k (video).  Will ffmpeg try to convert that video at 1000kb, or will it be smart enough to convert it at the same 700k?
