It stated things like "postage stamp-sized video," jumpyness, bad audio... all those problems that were inherent in the early versions of Quicktime and MPEG.
I'll play devil's advocate, and say they still exist.
- "postage stamp-sized video" isn't technically true, with the exception of vertical-video syndrome, and the occasional Youtube video that doesn't allow resizing to a larger play window.
- Jumpyness - occurs in Firefox. The video stops on one frame, then jumps ahead a few seconds. Audio plays smoothly during the freeze/jump portion.
- Bad audio - quite easy to encounter with a video having volume well out of whack, or simply have scratching all across the video.
All three problems are trivially solved, but still exist.
As for Bitcoin, any problems can be handled by an update to the reference protocol (one of which was required when some miner produced a block too large for some clients.)
