Yeah so why are you using a lower-quality MPEG-4 codec if you're already 
willing to cough up the licence fees?

For what it's worth, here are all the codecs which libavcodec classifies
as "risky", for patent or other reasons.  This is not legal advice, of
course, but it's something of a guide:

mpeg2video h263 h263p flv rv10 mpeg4 msmpeg4v1 msmpeg4v2 msmpeg4v3 wmv1
h263 mpeg4 msmpeg4v1 msmpeg4v2 msmpeg4v3 wmv1 wmv2 h263i flv rv10 rv20
svq1 svq3 wmav1 wmav2 indeo3 aac mpeg4aac

For comparison, here are codecs which libavcodec *does not* classify as 
"risky".  Keep in mind that some are not classified as "risky" because 
they have to be enabled at configure time.  This is almost certainly the 
case for mp3lame, for example.
