This syntax is outdated, the aac endocder is named libfaac now. 
All bitrates are used like given, so 300 is 300 bit and not 300 kbit, 
like in the past, so you should add a k (300k vor video and 96k vor 
sound).
So this one should work:
"ffmpeg -vcodec mpeg4 -b 300k -qmin 3 -qmax 5 -bufsize 4096 -g 300
-acodec libfaac -ab 96k -i /home/aurelio/Festival.divx -s 320x240
-aspect 4:3 /home/aurelio/Festival.mp4"

Yes, they use a very old version, so it works there.
