It would be nice if any solution could be optional. Some people think
it looks cool when a seek blends two unassociated I frames. ;) And
surely its faster to just not worry about it. Perhaps for UI issues
turn it off. Like on sliders and such. But when accuracy is needed,
like in a NLE, clearly want it to look better.

"INVALID" isn't really the proper terminology is it? This seems more
like an "unsynced" or "out of sequence" buffer.
