Hmm. I think the default (nothing) should be synonymous with 
"best-effort" (or "best") and leave it to the 
browser/os/codec/format/etc. as to what "best effort" actually is.
While "accurate" means as accurate as technically possible, even if it 
means increased resource use. I can see online video editing, subtitle 
syncing, closed caption syncing, and audio syncing being key usage 
examples of that.
And maybe a "simple" flag for when keyframe or second seeking and 
similar is good enough, preferring lower resource seeking.
So "best" ("" default) and "accurate" and "simple", that covers most 
uses right?
