x264 mixed_ref=0 issue
#4
I can reproduce the problem.
Strange.

=> I see the problem:
'veryfast':
- veryfast:
                                    --no-mixed-refs --rc-lookahead 10
                                    --ref 1 --subme 2 --trellis 0 --weightp 1
disables, the mixed-refs, and there is no option to enable it which Hybrid could use.

=> will fix tomorrow evening.
I will adjust Hybrid to not minimize to 'veryfast','superfast','ultrafast' unless '--no-mixed-refs' is enabled tomorrow.
