I only watched your video thru 12 min, 'coz my computer crashed for some reason after that, but I'll like to comment on two hands I absolutely disagree with icemonkey.
the 10-8s hand: your call was absolutely fine. 10-8s is a super strong hand on a 6-handed table esp. on the button! with only one raiser it's an easy call pre. (so being behind is a good thing, not a bad thing like icemonkey mentioned)
you should muck them if there's a raise and a reraise obv; or if you are out of position. But you should also make this call, let's say on the small blind, if there is a raise in front and one or more callers. You get the
odds that way. So your play was fine.
And no, do not ever limp at a 6handed table, even if it's the micromicro games. (you can also use the 6-handed cardschat preflop chart I put up on one thread, u can search my posts, it's great winner chart)
a-2s hand: limping in behind here was ok as well. I don't ever see a raise here tho (unlike icemonkey said). callin the 2*5raise is ok once the initial limper called but you shouldn't make this play too often, because it's not +ev.
