I reviewed this patch since I needed some additional features:
* Bugfix: In VBR mode, the SI-table period was calculated on the  
muxrate after it had been multiplied by 10. The resulting rates were  
10x to slow.
* Extra feature: Specifying a negative muxrate on the commandline  
overwrites the calculated muxrate, but still activates VBR.
* I added an additional patch which includes some additional info/ 
clarification and does not cause any changes in the compiled code.

This extra feature is needed to produce a VBR MPEG-TS by  
remultiplexing a source ("-{a,v}codec copy"), since the bitrates can't  
be learned from the stearm.

Attached patches are against r20080.
