Ok, I can add checks for additional sync code(s).

I'll also make it return a lower value when too few codes are found 
(AVPROBE_SCORE_MAX / 4 or AVPROBE_SCORE_MAX / 8), and only return 
AVPROBE_SCORE_MAX - 1 for too few codes if there is a WAV signature so that we 
tie with wav_probe, so that we get more probe bytes to see if more sync codes 
exist or not.

Hmm, actually I can only see raw dirac now, though that doesn't really qualify 
as 'some', I guess :)
