Avoiding keyframes does not really help. CBR obviously will not diverge 
from the given bandwidth, but it is not a requirement. I tested with VBR 
encoded movies and that works allright. VBR uses the given video 
bandwidth as an average, so it varies a bit. Typically an 750 b/s coded 
video with 300 b/s audio will occupy a bandwidth of 1-2 Mb/s.

As comparission:
- a 5 Mb/s VBR stream might go up to 8 Mb/s temporarily.
- a 8 Mb/s VBR stream might go up to 10 Mb/s temporarily.
