The role of substrate-induced microstructure on transport properties in c-axis oriented epitaxial Tl{sub 2}Ba{sub 2}CaCu{sub 2}O{sub x} films grown on LaAlO{sub 3} and SrTiO{sub 3} has been studied. For a magnetic field parallel to the Cu-0 planes, resistivity and the critical current density, J{sub c}, have been measured as a function of angle {theta} between the applied field and the direction of transport current. Resistivity dips and enhancement of the critical current density, J{sub c}, were observed for magnetic fields applied parallel to the substrate twins in LaAlO{sub 3} in high fields ({ge} 2 T). Meanwhile for films on SrTiO{sub 3}, resistivity and J{sub c} were Lorentz-force independent.
