Video 2:
5:12, BL: Either bet/(fold river or check/call for bluff induction. High wts = bet, low wts = check. Bet/call is too much as they don't bluff very often on these limits.
11:24, BL: I call him down if no draw arrives. http://www.pokerstrategy.com/strategy/fixed-limit/58/
18:40, UL: Either raise the flop directly or check/raise the turn but don't call flop, donkbet turn. You lose too much value this way. He won't raise too often here and if he would he would even raise after you check/raised the flop.
19:24, UR: Don't donkbet here. Either check/raise or check/call. I prefer check/raise as he will calldown a lot worse hands if he thinks that you are bluffing at him.
19:32, BL: T7o is an openraise here.
20:40, UL: I prefer bet/fold turn for a free showdown morethan check behind.
22:24, UL: KJs is the lowest hand I would raise here but it plays very well even multiway and you don't have to bet on the flop if you don't hit. As played you should bet the flop. With no preflopaggressor the chance that they take a freecard is too high and you might get more action with a bet than with a check/raise as this looks weaker.
Wow check/call on a 2-suited flop is nothing I like.
24:24, BL: I like a call on the river more for overcalls. You often gain the same but you lose less if he has AJ or JJ (I wrote JJ before seeing his hand *g*).
25:12, BL: More a bad habit in my opinion. Better Check/raise here and make him calldown A-high putting you on a draw. You also can fold pretty easily if he raises the turn or river.
26:55, BL: Just raisethe flop. If he checks the turn to you you lost a lot money.
27:30, BL, QJO should be good enough to isolate him.
29:08, UL: Wow you like donking. 
I think check/call once for your outs is fine as well as check/fold if he is too tight.
30:09, UL: Even with the 3rd calling it isn't worth calling here in my opinion. You call for setvalue but you don't hit it often enough here.
33:36, BL: Try to steal the pot with a bet on the flop. 
34:04, UL: Check/raise flop instead of donkbet.
As played 3-bet. You yourself raised donkbets with A-high earlier so I see him doing this often enough as well.
35:16, BL: J8o doesn't play very well against callingstations. Be rather a bit tighter than looser against them.
36:52, UR: Check behind river. No worse hand will fold here and you are ahead against a busted straight- or flushdraw anyway which won't call anymore.
Most of the time you should check behind A- and K-high as the chance of winning with them is too high to risk being bluffraised or being called by a better hand.
37:04, BL: ATs is strong enough for a 3-bet here. River as played is difficult. I think check/fold is ok here on this ugly board.
38:22, UR: A pair is pretty strong in a blind battle. Call at least the flop. I like a turnraise a lot for a free showdown.
Here's the stats for the period in the graph.
In HU it's usually + though, so just depends on how you play.
