I have been using Flash player for many years, and remember the good old days when Macromedia owned it. I don't recall during this time the need for constant updates, which I believe to be a major problem with issues of playing online videos. I really don't understand why Adobe have this constant need to issue updates, and beta versions? Why can't they get it right with a couple of updates per year? The same is with their Air player.
There are three kinds of updates:
2 and 3 are usually scheduled updates, 1 may be released out of schedule.
Scheduled updates are about 8 per year, out-of-schedules are unpredictable.
