yes, it seems ok to me to place VOL headers at I-frames (different VOs in a
row then). However we also write a VOL-header for p-frames if quantizer type
changes in "modulated quant" mode. I'm pretty sure this is not ok (but it
could be easily fixed by removing the "modulated quant" option, imho there's
no gain from it anyway)...
