My SGT10.1 also uses the Tegra 2 and it plays those videos without any problems. Try VPlayer or MX PLayer (I assume you have already). I find VPlayer to get things right that other players won't.
Dice Player works but not flawlessly....it jerks sometimes. The latest MX Player update also seems to work ... it's just not totally smooth. Will try Vplayer tonight
